# des_undes # DES/UNDES V1.1.0 source reconstruction — v2
Old des/undes code based on libdes-3.14. This directory contains a revised C reconstruction of `des.exe` and
`undes.exe` after comparison with the original `cryptl99.zip` dependency.
## Main files
- `des.c` — reconstructed encryption program
- `undes.c` — reconstructed decryption program
- `des_common.c`, `des_common.h` — reconstructed common support
- `reconstruction-notes.md` — evidence, file format and remaining uncertainty
- `cryptlib-api-map.md` — exact CRYPTLIB 0.99 function mapping
- `validation.md` — build/round-trip sanity check
- `asm/` — disassembly used for the reconstruction
- `third_party/cryptl99.zip` — user-supplied original archive
- `third_party/cryptlib-0.99/` — extracted dependency source
## What changed from the first reconstruction
The supplied CRYPTLIB source resolves several earlier uncertainties and one
important mistake:
1. The real API names are lower-case (`initLibrary`,
`queryAlgoModeInformation`, `retrieveIV`, etc.).
2. The executable uses `CRYPT_ALGO_3DES`, not `CRYPT_ALGO_DES`.
3. The mode is `CRYPT_MODE_CBC`.
4. The effective queried key size is 14 bytes.
5. The queried/stored IV is 4 bytes, not 8 bytes.
6. The archive contains exactly libdes 3.14, matching the embedded executable
version string.
## Status
The control flow and file-format reconstruction is high confidence. The code
is intended primarily as a faithful readable reconstruction. It has not been
claimed to be byte-for-byte recompilable to the original executables because
that would require the exact original compiler flags, source layout, linker
configuration and original identifiers.

# CRYPTLIB 0.99 API mapping
The supplied `cryptl99.zip` removes the remaining uncertainty about the
CRYPTLIB calls. The executable's call shapes, local structure offsets and the
source in `crypt.h`/`crypt.c` all agree.
| Operation | CRYPTLIB 0.99 function | des.exe target | undes.exe target |
|---|---|---:|---:|
| Initialise library | `initLibrary()` | `00B3:0738` | `00B7:072A` |
| End library | `endLibrary()` | `00B3:0746` | `00B7:0738` |
| Query algorithm/mode | `queryAlgoModeInformation()` | `00B3:0566` | `00B7:0558` |
| Query context | `queryContextInformation()` | `00B3:06EC` | `00B7:06DE` |
| Initialise context | `initCryptContext()` | `00B3:0756` | `00B7:0748` |
| Destroy context | `destroyCryptContext()` | `00B3:0940` | `00B7:0932` |
| Load key | `loadCryptContext()` | `00B3:09C5` | `00B7:09B7` |
| Retrieve IV | `retrieveIV()` | `00B3:0BA9` | — |
| Load IV | `loadIV()` | — | `00B7:0A90` |
| Encrypt | `encryptBuffer()` | `00B3:0C1E` | — |
| Decrypt | `decryptBuffer()` | — | `00B7:0CEC` |
## Algorithm values
Both mains store the integer value `3` for the algorithm and `3` for the mode.
In the supplied `crypt.h` these are:
```c
CRYPT_ALGO_3DES == 3
CRYPT_MODE_CBC == 3
```
So DES/UNDES V1.1.0 uses **two-key triple DES in CBC mode**.
The `CRYPT_QUERY_INFO` offsets used by the machine code also match the supplied
header in the 16-bit large memory model. The program reads:
- `keySize` = 14 bytes (112 bits)
- `ivSize` = 4 bytes (32 bits)
Those are exactly the recommended values in the CRYPTLIB 0.99 `3DES-CBC`
capability entry.

# Reconstruction notes — DES/UNDES V1.1.0
## Confidence
The main program logic is now reconstructed with high confidence. The supplied
`cryptl99.zip` is especially useful because it contains the exact CRYPTLIB 0.99
API and libdes 3.14 source that was linked into the executables.
This is **not** the original source text. Original variable names, comments,
whitespace and file decomposition were not retained in the executable. Names
such as `firstTime`, `passwordBlock`, `negativeMarker`, and the split into
`des_common.c`/`.h` are descriptive reconstruction choices.
## Compiler and memory model
Both programs are 16-bit MS-DOS MZ executables and contain the runtime string:
`Turbo-C - Copyright (c) 1988 Borland Intl.`
The generated code uses far data pointers extensively, and `malloc()` returns a
segment:offset pointer. That is consistent with a Turbo C large-memory-model
build.
## Exact crypto dependency
The executables contain:
`libdes v 3.14 - eay`
The supplied CRYPTLIB archive contains the same `libdes/version.h` string, plus
`crypt.h`, `crypt.c`, `lib_3des.c` and the relevant libdes sources. This is the
actual dependency family used by the executables rather than merely a later
compatible library.
## Important correction: it is 3DES
The machine code assigns value 3 to both the algorithm and mode variables.
According to the supplied `crypt.h`:
- `CRYPT_ALGO_3DES` = 3
- `CRYPT_MODE_CBC` = 3
Therefore the encryption is **two-key 3DES-CBC**, despite the executable being
called `des.exe`.
`crypt.c` defines the recommended 3DES-CBC parameters as:
- key size: 112 bits = 14 bytes
- IV size: 32 bits = 4 bytes
- DES block size: 64 bits = 8 bytes
The main routine obtains both sizes through `queryAlgoModeInformation()`.
## Password handling
The command-line password is copied directly into a 14-byte key buffer and is
zero-padded if shorter. Characters after byte 14 do not influence encryption.
There is no password hash or KDF in the DES/UNDES layer.
CRYPTLIB's `des3InitKey()` then constructs the two DES key schedules from that
user-key buffer. `des_check_key` in the bundled libdes defaults to zero, so
parity/weak-key checking is not enabled by default.
## File layout
For a non-empty encrypted input the file is:
```text
Offset Size Meaning
0 4 file version: 0x00002775
4 4 CRYPTLIB-recommended CBC IV
8 256 encrypted password-check block
264 16384 encrypted data block 1
16648 16384 encrypted data block 2
... ...
```
For an empty input, `des.exe` writes only the four-byte version. Because no
`encryptBuffer()` call with data occurs, no IV or password-check block is
written.
## Data-block layout before encryption
Each 16384-byte encrypted data block consists of:
```text
0..3 signed 32-bit length marker
4..7 signed 32-bit secondary marker
8..16383 at most 16376 bytes input data
```
For a partial final block, the first field is the positive plaintext byte count.
For a full block it is a negative value; `undes.exe` interprets any negative
value as exactly 16376 plaintext bytes.
The full-block negative value is formed from the absolute value of the first
signed 16-bit word of the plaintext and then negated. If that produces zero,
`-1` is stored instead. The second field is also a negative marker derived from
a signed 16-bit plaintext word. `undes.exe` does not use this second field.
The exact purpose of the secondary marker cannot be established from the
executables alone; its computation is established, its design intent is not.
## CBC ordering on the first block
An unusual but confirmed detail is the first-block ordering.
`des.exe` performs the cryptographic operations in this order:
1. encrypt first 16 KiB data block
2. retrieve the now-generated IV
3. encrypt the 256-byte password-check block
but writes:
1. IV
2. encrypted password-check block
3. encrypted first data block
`undes.exe` reads the stored password block and first data block, then decrypts
in cryptographic order:
1. decrypt first data block
2. decrypt password-check block
This preserves the CBC state exactly. The apparent storage/processing order
mismatch is therefore intentional in the program logic, not a decompiler error.
## Password-check block
Before encryption, the first 14 bytes of the 256-byte password-check block are
the derived 14-byte key. The executable does not initialise the remaining 242
bytes before encrypting the block. During decryption only the first 14 bytes
are compared.
## Uninitialised bytes in the final data block
`des.exe` always encrypts the complete 16384-byte buffer. If the final input
chunk is shorter than 16376 bytes, the unused tail is not explicitly cleared
first. This is also visible in the machine code. UNDES writes only the number
of plaintext bytes stored in the first 32-bit field.
## Error handling and robustness
Read errors are detected only when `read()` returns `-1`; short reads are not
rejected. `undes.exe` does not authenticate ciphertext and does not validate a
positive decrypted length against 16376 before passing it to `fwrite()`. These
are normal limitations for small DOS-era utility code, but they matter if old
encrypted files are corrupted or attacker-controlled.
## Remaining uncertainty
The following cannot be recovered exactly without original source/debug
symbols:
- original variable/function names for the DES/UNDES-specific code;
- original comments and formatting;
- exact source-file decomposition;
- the design rationale for the secondary 32-bit marker;
- the symbolic name/formula originally used for file version `0x2775`.
The actual program behaviour no longer depends on guessed CRYPTLIB API names.

After much procrastinating I'm finally ready to release the initial version of
my encryption library. I wrote this in response to random requests I keep
seeing in various newsgroups for encryption libraries, usually with no
responses. This library provides a (hopefully) universal interface to all
kinds of conventional-key encryption algorithms in an easy-to-use manner. The
library is divided into two parts:
1. Routines to query the library capabilities.
2. Routines to perform the en/decryption.
The library currently provides the following encryption algorithms and modes:
MDC/SHS CFB
DES ECB, CBC, CFB, OFB, PCBC
3DES ECB, CBC, CFB, OFB
IDEA ECB, CBC, CFB, OFB
RC4
SAFER ECB, CBC, CFB, OFB
SAFER-SK ECB, CBC, CFB, OFB
Notes:
1. The Visual Basic interface hasn't been tested much. If someone could do
a Delphi interface and a VBX or OCX version that'd be nice.
2. A proper configure script with everything would be nice for Unix users.
Anyone want to create one of these?
3. Optimised asm implementations of some of the routines would be useful.
There are 80x86 and 68K asm routines included for IDEA and RC4, but I
haven't had time to tie them into the code yet. I have 386+ asm code for
SHA, but need to tie that in as well. Volunteers?
Requirements for a Standard Encryption Library
----------------------------------------------
- It should be idiot-proof.
It's quite difficult to implement insecure encryption using this code without
actually trying.
- It should provide extensive error checking.
Each parameter and function call is checked for errors before any actions are
performed, with error reporting down to the level of individual parameters.
- It should be portable.
The library is written entirely in ANSI C, with hooks for certain OS-specific
oddities such as Windows/OS/2 dynamic link libraries. The only external
routines used are ones from <string.h> and one call from <time.h>.
- It should be extendable.
The library provides the capability to add encryption capabilities at runtime
(currently only partially implemented, since the interface is somewhat messy
- you need to pass in about 15 parameters to do it).
- It should be free of silly restrictions.
This software is distributed as copyrighted freeware, with copyrights on
individual encryption modules being held by the contributing authors. You
are free to use the code in any way you want, with the following
restrictions:
If you make any changes to the code, you should send a copy of the changes
to the author or authors to allow them to integrate the changes into the
code. This is to allow a central consistent version to be maintained.
If you use the library as part of a product, you should offer a copy to the
author or authors of the library routines you are using. This is to let
the authors know that their work is being usefully applied.
Any commercial software you create with this code may not be merely a set
or subset of the encryption libraries, with or without minor added
functionality. This is to stop people adding their own wrappers and
selling it as "their" encryption product.
These terms are pretty much identical the the library GPL, which seem to be
about the least restrictive usage terms around apart from outright public
domain software.
- It should be buzzword-complete.
The library is written in C, but is basically laid out as a C++ class
library. It can work as a static library, a shared library, or a dynamic
link library. It'll even work with things like Visual Basic.
Library Basics
--------------
Like the standard C file I/O libraries which work with FILE objects, this
library works with an "encryption context" of type CRYPT_INFO. To encrypt
data, you create an encryption context, load a user key into it, en/decrypt
data, and destroy it when you've finished. This concept lends itself to
implementation either as a C++ class or as C routines. Throughout this
document all examples are given in C, translation to C++ is a simple step.
The overall library structure is as follows:
Library core Plug-in
modules
+---------------+------------+
| | MDC/SHS |
| +------------+
| | DES |
| +------------+
/ \ | Crypt | Triple DES |
User / ---- \ | +------------+
Programs \ ---- / | Library | IDEA |
\ / | +------------+
| API | RC4 |
| +------------+
| | Safer |
| +------------+
| | others |
+---------------+------------+
The library API serves as an interface to a range of plug-in encryption modules
which allow encryption algorithms to be added in a fairly transparent manner.
The standardised API allows any of the algorithms and modes supported by the
library to be used with a minimum of coding effort. As such the main function
of the library is to provide a standard, portable, easy-to-use interface
between the underlying encryption routines and the user software.
Portability
-----------
All data made accessible through the library API is in big-endian format. The
library automatically takes care of endianness conversion to the form used by
the local system in a manner invisible to the end user.
All code is plain ANSI C, with no machine or OS-specific functions or calls
being used.
Creating/Destroying Encryption Contexts
---------------------------------------
When you create an encryption context, you must specify the encryption
algorithm and mode you want to use for that context. The encryption algorithms
and modes are given in the crypt.h file, and are updated along with the library
itself. For example, to create and destroy an encryption context for DES in
CBC mode, you would use the following code:
CRYPT_INFO cryptInfo;
initCryptContext( &cryptInfo, CRYPT_ALGO_DES, CRYPT_MODE_CBC );
/* Perform en/decryption */
endCryptContext( &cryptInfo );
The initCryptContext() and endCryptContext() functions take care of issues like
initialization, memory management, and erasure of data after use.
Loading Keys into Encryption Contexts
-------------------------------------
Once an encryption context has been created, you need to load a key into it.
This is done with the loadCryptContext() function. For example to load the key
"Secret key" into the previously-created encryption context you would use:
loadCryptContext( &cryptInfo, "Secret key", 10 );
Some hardware modules which enforce red/black seperation will not allow
plaintext keys to pass across the library interface. In this case the key
parameter passed to loadCryptContext() will be a key selector or key encryption
key to be passed to the underlying hardware. For example to pass a key
selector to a key stored inside a DES hardware module you would use:
loadCryptContext( &cryptInfo, &keySelector, sizeof( keySelector ) );
You can also load an IV into the context, although for encryption you would
usually leave this to the library to perform automatically. To load an IV you
would use:
loadIV( &cryptInfo, iv, ivSize );
To retrieve an IV which has been generated by the library you would use:
retrieveIV( &cryptInfo, iv );
The loadCryptContext(), loadIV(), and retrieveIV() functions take care of
issues like initialization, memory management, endianness conversion, and key
setup.
If you need to reserver space for keys and IV's, you can use the
CRYPT_MAX_KEYSIZE and CRYPT_MAX_IVSIZE defines from crypt.h to determine the
mount of memory you need. No key or IV used by the library will ever need more
storage than the settings given in these defines.
Encrypting/Decrypting Data
--------------------------
Now that the encryption context and (if necessary) IV are set up, you're ready
to encrypt or decrypt data. To encrypt or decrypt a block of data you use:
encryptBuffer( &cryptInfo, buffer, length );
and:
decryptBuffer( &cryptInfo, buffer, length );
If a block encryption mode is being used, these functions will recognise a call
with length == 0 as a courtesy call to indicate that this is the last data
block and will take whatever special action is necessary for this case.
Extended Initialization
-----------------------
The initCryptContext() has a companion function initCryptContextEx() which may
be used to perform an extended, algorithm-specific initialisation. The second
parameter passed to the function is an algorithm-dependant structure used to
specify extra information to be used in the initalisation. Not all algorithms
will support extended initialisation parameters. If they are supported, the
structures have the name CRYPT_INFO_<algorithm_name>, and are laid out as
follows:
Structure CRYPT_INFO_MDCSHS:
/* The number of iterations used during the key setup process triggered
by a loadCryptContext() call. Using a high value (500 or more) will
greatly slow down password-guessing attacks by making the key setup
process painfully slow. Values in the range of 50-100 are recommended for
most systems */
int keySetupIterations;
Structure CRYPT_INFO_SAFER:
/* The number of rounds of encryption. The default settings are 6 rounds for
SAFER-K64, 8 rounds for SAFER-SK64, and 10 rounds for SAFER-K128 and
SAFER-SK128 */
int rounds;
/* Whether to use SAFER or SAFER-SK. The default is to use the original
algorithm SAFER. SAFER-SK is a version which improves the key schedule to
eliminate some possible weaknesses when SAFER is used as a keyed hash
function */
BOOLEAN useSaferSK;
Error Checking
--------------
When the library is initialised, each of the built-in encryption algorithms
goes through a self-test procedure which checks the implementation using
standard test vectors and methods given with the algorithm specification
(typically FIPS publications, ANSI standards, or standard reference
implementations). This self-test is used to verify that each encryption
algorithm is performing as required.
Each function in the library performs extensive error checking (although
monitoring of error codes has been left out in the following code samples for
readability). The file TEST.C, included with the crypt library, includes
better error handling than the short examples below.
For functions which complete with no error, the library will return CRYPT_OK.
For functions which complete with some form of error internal to the library
itself, the library will return CRYPT_ERROR (this situation should never occur
and should be reported to the library authors).
If the encryption code or hardware fails an internal self-test, the library
will return CRYPT_SELFTEST if an attempt is made to use the encryption module
which failed the self-test.
If there is a problem with a parameter passed to a library function, the
library will return one of CRYPT_BADPARM1 ... CRYPT_BADPARM15 depending on the
parameter in error, or simply CRYPT_BADPARM if it cannot resolve the exact
parameter error type.
General resource and programming errors are flagged by the return values
CRYPT_NOMEM for a lack of memory, CRYPT_NOTINITED if you try to use an
encryption context hasn't been initialised yet or which has been destroyed,
CRYPT_INITED when you try to re-initialise an encryption context or re-load an
encryption key, CRYPT_NOALGO or CRYPT_NOMODE if the requested encryption
algorithm or mode is unavailable, CRYPT_NOKEY if the encryption key hasn't been
loaded into an encryption context, and CRYPT_NOIV if the IV hasn't been loaded
into an encryption context.
The macros isStatusError() and isStatusOK() can be used to determine whether a
return value denotes an error condition, for example:
int status;
status = initCryptContext( &cryptInfo, CRYPT_ALGO_IDEA, CRYPT_MODE_CFB );
if( isStatusError( status ) )
/* Perform error processing */
Examples
--------
The following examples have had error checking removed for readability. See
the test code in TEST.C for an example with full error checking.
To encrypt a buffer using DES in CFB mode with the password 0x12345678ABCDEF:
CRYPT_INFO cryptInfo;
BYTE key[] = { 0x12, 0x34, 0x56, 0x78, 0xAB, 0xCD, 0xEF };
/* Load the key, encrypt the buffer (the IV is automatically generated
if we don't specify one, it can be obtained with retrieveIV()), and
destroy the encryption context */
initCryptContext( &cryptInfo, CRYPT_ALGO_DES, CRYPT_MODE_CFB );
loadCryptContext( &cryptInfo, key, sizeof( key ) );
encryptBuffer( &cryptInfo, buffer, length );
destroyCryptContext( &cryptInfo );
To hash an arbitrary-size passphrase down to the one used by a particular
cryptosystem (in this case triple DES) using MDC/SHS:
CRYPT_QUERY_INFO cryptQueryInfo;
CRYPT_INFO cryptInfo;
BYTE key[ 100 ];
int keySize, ivSize;
/* Find out how long we can make the key */
queryAlgoModeInformation( CRYPT_ALGO_3DES, CRYPT_MODE_CBC,
&cryptQueryInfo );
keySize = cryptQueryInfo->maxKeySize; /* Use all we can */
ivSize = cryptQueryInfo->ivSize;
/* Encrypt a null data block using a null IV with the passphrase as the
key. This works vaguely like the Unix password encryption except
that we don't have a salt (which would be the IV) */
memset( key, 0, keySize );
initCryptContext( &cryptInfo, CRYPT_ALGO_MDCSHS, CRYPT_MODE_CFB );
loadCryptContext( &cryptInfo, passphrase, strlen( passphrase ) );
loadIV( &cryptInfo, key, ivSize );
encryptBuffer( &cryptInfo, key, keySize );
destroyCryptContext( &cryptInfo );
To encrypt a file using triple DES in CBC mode with the key generated in the
previous example:
BOOLEAN firstTime = TRUE;
/* Load the previously-generated key */
initCryptContext( &cryptInfo, CRYPT_ALGO_3DES, CRYPT_MODE_CBC );
loadCryptContext( &cryptInfo, key, keySize );
/* Copy the data across, encrypting as we go */
while( ( length = fread( buffer, 1, BUFSIZE, inFile ) ) != 0 )
{
/* Encrypt the data in the buffer */
encryptBuffer( &cryptInfo, buffer, length );
/* If it's the first block, retrieve the IV and prepend it to the
output data. Note the since we've let the library generate the
IV for us automatically, we can't retrieve it until after the first
encryptBuffer() call */
if( firstTime )
{
CRYPT_QUERY_INFO cryptQueryInfo;
BYTE iv[ CRYPT_MAX_IVSIZE ];
int ivSize;
/* Find out how long the IV we're using is */
queryContextInformation( &cryptInfo, &cryptQueryInfo );
ivSize = cryptQueryInfo->ivSize;
/* Retrieve the IV and write it to the output file */
retrieveIV( &cryptInfo, iv );
fwrite( iv, 1, ivSize, outFile );
firstTime = FALSE;
}
/* Write the encrypted data to the output file */
fwrite( buffer, 1, length, outFile );
}
/* Since CBC is a block cipher, we perform a courtesy close call to let
the encryption routines handle the last block */
encryptBuffer( &cryptInfo, buffer, 0 );
destroyCryptContext( &cryptInfo );
To decrypt the previously encrypted file with the key generated in the previous
example:
CRYPT_QUERY_INFO cryptQueryInfo;
BYTE iv[ CRYPT_MAX_IVSIZE ];
int ivSize;
/* Load the previously-generated key */
initCryptContext( &cryptInfo, CRYPT_ALGO_3DES, CRYPT_MODE_CBC );
loadCryptContext( &cryptInfo, key, keySize );
/* Find out how long the IV we're using is */
queryContextInformation( &cryptInfo, &cryptQueryInfo );
ivSize = cryptQueryInfo->ivSize;
/* Read the IV from the input file and load it into the encryption
context */
fread( iv, 1, ivSize, inFile );
loadIV( &cryptInfo, iv, ivSize );
/* Copy the data across, decrypting as we go */
while( ( length = fread( buffer, 1, BUFSIZE, inFile ) ) != 0 )
{
/* Encrypt the data in the buffer */
decryptBuffer( &cryptInfo, buffer, length );
/* Write the decrypted data to the output file */
fwrite( buffer, 1, length, outFile );
}
/* Since CBC is a block cipher, we perform a courtesy close call to let
the encryption routines handle the last block */
decryptBuffer( &cryptInfo, buffer, 0 );
destroyCryptContext( &cryptInfo );
A longer usage example including proper error checking and with various other
test routines can be found in the file test.c included with the code.
Querying the Encryption Library Capabilities
--------------------------------------------
The previous examples showed the use of the queryAlgoModeInformation() and
queryContextInformation() calls to retrieve information about the
characteristics of a particular algorithm as implemented by the encryption
library. There are four such calls in total, of which two query the existence
of an implementation of an algorithm or algorithm/mode combination, and two
return information about the implementation.
The library can be interrogated about the existence of a particular encryption
algorithm or algorithm and encryption mode combination with:
status = queryAlgoAvailability( algorithm );
or:
status = queryModeAvailability( algorithm, mode );
In addition to requesting information on the availability of an encryption
algorithm and mode, you can request extra information to be returned in a
CRYPT_QUERY_INFO structure with:
status = queryAlgoModeInformation( algorithm, mode, &cryptQueryInfo );
or
status = queryContextInformation( &cryptInfo, &cryptQueryInfo );
with the former being used to request information on a given algorithm/mode
combination and the latter being used to request information about the
encryption context being used.
The CRYPT_QUERY_INFO structure contains the following fields:
/* The encryption algorithm, encryption mode, and general algorithm name
as an ASCII string */
CRYPT_ALGO cryptAlgo;
CRYPT_MODE cryptMode;
char *algoName;
/* The algorithm block size in bytes, the minimum, recommended, and
maximum key size in bytes, and the minimum, recommended, and maximum
IV size in bytes */
int blockSize;
int minKeySize;
int keySize;
int maxKeySize;
int minIVsize;
int ivSize;
int maxIVsize;
/* The algorithm speed relative to a block copy operation. This value
ranges from 1 ... CRYPT_MAX_SPEED, or CRYPT_ERROR if no speed rating is
available */
int speed;
Algorithm-Specific Notes
------------------------
MDCSHS:
None
DES:
loadCryptContext() will return a bad parameter code if the DES key parity is
wrong or if the key is a weak key (CRYPT_BADPARM2 in this case).
encryptBuffer() and decryptBuffer() will return a bad parameter code if the
encryption mode is ECB, CBC, or PCBC and the encrypted data length is not a
multiple of the block size (CRYPT_BADPARM3 in this case).
Triple DES:
loadCryptContext() will return a bad parameter code if the DES key parity is
wrong or if the key is a weak key (CRYPT_BADPARM2 in this case).
encryptBuffer() and decryptBuffer() will return a bad parameter code if the
encryption mode is ECB or CBC and the encrypted data length is not a multiple
of the block size (CRYPT_BADPARM3 in this case).
IDEA:
encryptBuffer() and decryptBuffer() will return a bad parameter code if the
encryption mode is ECB or CBC and the encrypted data length is not a multiple
of the block size (CRYPT_BADPARM3 in this case).
The IDEA algorithm is patented by Ascom Systec AG, CH-5506 Maegenwil,
Switzerland, ph. +41 64 56 59 45, email idea@ascom.ch, and cannot be used
commercially without a license. As of June 1995, the licensing terms were
120 SFr (about US$90) per user for 1-10 users, 80 Sfr (about US$60) per user
for 11-20 users, and 60 Sfr (about US$46) per user for 21-100 users.
RC4:
None
SAFER:
SAFER-SK:
encryptBuffer() and decryptBuffer() will return a bad parameter code if the
encryption mode is ECB or CBC and the encrypted data length is not a multiple
of the block size (CRYPT_BADPARM3 in this case).
Plug-In Module Implementation
-----------------------------
These notes are rather brief since there is a lot of ground to cover, and the
easiest way to see what is required is to look at the crypt.c code and the way
it interfaces to the lib_XXX.c code, which may be regarded as standard
implementations of a plug-in module (the triple DES and IDEA modules are
probably the best examples). Basically, implementors must provide the
following services in their plug-in modules:
int selfTestFunction( void );
Perform a self-test on the encryption hardware/software module. This
function is called once before any other function is called.
int initFunction( CRYPT_INFO *cryptInfo );
Initialise the appropriate private CRYPT_INFO fields.
int initExFunction( CRYPT_INFO *cryptInfo, void *cryptInfoEx );
Initialiase the appropriate private CRYPT_INFO fields based on the extended
information given in the second parameter.
int endFunction( CRYPT_INFO *cryptInfo );
Clear the appropriate private CRYPT_INFO fields.
int initKeyFunction( CRYPT_INFO *cryptInfo );
Initialise the internal key based on the user key. Typically this might
perform one or more of the following:
Hash the user key down to the size of the key used by the algorithm
Perform some type of key schedule operation
Perform endianness conversion for the current operating environment
Load the key into external crypto hardware.
Perform a key selection in external hardware based on the specified key
selector.
For algorithms with asymmetric internal keys, both an encryption and a
decryption key will have to be generated, as a crypt context may be used for
encryption or decryption.
int initIVFunction( CRYPT_INFO *cryptInfo );
Initialise the IV. Typically this might perform one or more of the
following:
Perform endianness conversion for the current operating environment
Load the IV into external crypto hardware.
int encryptFunction( CRYPT_INFO *cryptInfo, void *buffer, int length );
int decryptFunction( CRYPT_INFO *cryptInfo, void *buffer, int length );
Encrypt/decrypt a block of data based on the algorithm and keying information
in CRYPT_INFO. Some algorithms may require special handling for the last
block (eg block truncation in CBC) so both routines should recognise a call
with length = 0 to indicate the end of the encrypted data block.

/*
* idea.c - C source code for IDEA block cipher.
* IDEA (International Data Encryption Algorithm), formerly known as
* IPES (Improved Proposed Encryption Standard).
* Algorithm developed by Xuejia Lai and James L. Massey, of ETH Zurich.
* This implementation modified and derived from original C code
* developed by Xuejia Lai.
* Zero-based indexing added, names changed from IPES to IDEA.
* CFB functions added. Random number routines added.
*
* Extensively optimized and restructured by Colin Plumb.
*
* There are two adjustments that can be made to this code to
* speed it up. Defaults may be used for PCs. Only the -DIDEA32
* pays off significantly if selectively set or not set.
* Experiment to see what works best for your machine.
*
* Multiplication: default is inline, -DAVOID_JUMPS uses a
* different version that does not do any conditional
* jumps (a few percent worse on a SPARC), while
* -DSMALL_CACHE takes it out of line to stay
* within a small on-chip code cache.
* Variables: normally, 16-bit variables are used, but some
* machines (notably RISCs) do not have 16-bit registers,
* so they do a great deal of masking. -DIDEA32 uses "int"
* register variables and masks explicitly only where
* necessary. On a SPARC, for example, this boosts
* performace by 30%.
*
* The IDEA(tm) block cipher is covered by patents held by ETH and a
* Swiss company called Ascom-Tech AG. The Swiss patent number is
* PCT/CH91/00117, the European patent number is EP 0 482 154 B1, and
* the U.S. patent number is US005214703. IDEA(tm) is a trademark of
* Ascom-Tech AG. There is no license fee required for noncommercial
* use. Commercial users may obtain licensing details from Dieter
* Profos, Ascom Tech AG, Solothurn Lab, Postfach 151, 4502 Solothurn,
* Switzerland, Tel +41 65 242885, Fax +41 65 235761.
*
* The IDEA block cipher uses a 64-bit block size, and a 128-bit key
* size. It breaks the 64-bit cipher block into four 16-bit words
* because all of the primitive inner operations are done with 16-bit
* arithmetic. It likewise breaks the 128-bit cipher key into eight
* 16-bit words.
*
* For further information on the IDEA cipher, see the book:
* Xuejia Lai, "On the Design and Security of Block Ciphers",
* ETH Series on Information Processing (ed. J.L. Massey) Vol 1,
* Hartung-Gorre Verlag, Konstanz, Switzerland, 1992. ISBN
* 3-89191-573-X.
*
* This code runs on arrays of bytes by taking pairs in big-endian
* order to make the 16-bit words that IDEA uses internally. This
* produces the same result regardless of the byte order of the
* native CPU.

;A while ago I posted a message claiming a speed of 238,000
;bytes/sec for an implementation of IDEA on a 33Mh 486. Below is
;an explanation and some code to show how it works. The basic
;trick should be useful on many (but not all) processors. I
;expect only those familiar with IDEA and its reference
;implementation will be able to follow the discussion. See:
;
;Lai, Xueja and Massey, James L. A Proposal for a New Block
;Encryption Standard, Eurocrypt 90
;
;For those who have been asking for the code, sorry I kept
;putting it off. I wanted to get it out of Turbo Pascal
;ideal-mode, but I never had the time.
;
;Colin Plum wrote IDEA-386 code which is included in PGP
;2.3a and uses the same tricks. I don't know who's is
;faster, but I expect they will be very close. Now
;here's how it's done.
;
;A major bottleneck in software IDEA is the mul() routine, which
;is used 34 times per 64 bit block. The routine performs
;multiplication in the multiplicative group mod 2^16+1. The two
;factors are each in a 16 bit word, and the output is also in a 16
;bit word. Note that 0 is not a member of the multiplicative
;group and 2^16 does not fit in 16 bits. We therefor use the 0
;word to represent 2^16. Now group elements map one to one onto
;all possible 16 bit words, since 2^16+1 is prime.
;
;Here is (essentially) the reference implementation from [Lai].
;
;
;unsigned mul( unsigned a, unsigned b ) {
; long int p ;
; long unsigned q ;
; if( a==0 ) p= 0x00010001 - b ;
; else if( b==0 ) p= 0x00010001 - a ;
; else {
; q= a*b;
; p= (q & 0xffff) - (q>>16)
; if( p<0 ) p= p + 0x00010001 ;
; }
; return (unsigned)(p & 0xffff) ;
;}
;
;
;Note the method of reducing a 32 bit word modulo 2^16-1. We
;subtract the high word from the low word, and add the modulus
;back if the result is less than 0. [Lai] contains a proof that
;this works, and you can convince yourself fairly easily.
;
;To speed up this routine, we note that the tests for a=0 and b=0
;will rarely be false. With the possible exception of the first 2
;of the 34 multiplications, 0 should be no more likely than any of
;the other 65535 numbers. Note that if (and only if) either a or
;b is 0 then q will also be 0, and we can check for this in one
;instruction if our processor sets a zero flag for multiplication
;(as the 68000 does but 80x86 does not).
;
;Fortunately p will also be zero after the subtraction if and only
;if either a or b is 0. Proof: r will be zero when the high order
;word of q equals the low order word, and that happens when q is
;divisible by 00010001 hex. Since 00010001h = 2^16+1 is prime,
;this happens if either a or b is a multiple of 2^16+1, and 0 is
;the only such multiple which will fit in a 16 bit word.
;
;The speed-up strategy is to proceed under the assumption that a
;and b are not 0, check to be sure in one instruction, and
;recompute if the assumption was wrong. Here's some 8086
;assembler code:
;
; mov ax, [a]
; mul [b] ; ax is implied. q is now in DX AX
; sub ax, dx ; mod 2^16+1
; jnz not0 ; Jump if neither op was 0. Usually taken.
;
; mov ax, 1 ; recompute result knowing one op is 0.
; sub ax, [a]
; sub ax, [b]
; jmp out ; Just jump over adding the carry.
;not0:
; adc ax, 0 ; If r<0 add 1, otherwise do nothing.
;out: ; Result is now in ax
;
;
;Note that when r<0 we add 1 instead of 2^16+1 since the 2^16 part
;overflows out of the result. The "adc ax, 0" does all the work
;of checking for a negative result and adding the modulus if
;needed.
;
;The multiplication takes 9 instructions, 4 of which are rarely
;executed. I believe similar tricks are possible on many
;processors. The one drawback to the check-after-multiply tactic
;is that we can't let the multiply overwrite the only copy of an
;operand.
;
;Note that most software implementations of IDEA will run at
;slightly different speeds when 0's come up in the multiply
;routine. The reference implementation is faster on 0, this one
;is faster on non-zero. This may be a problem for some real-time
;stuff, and also suggests an attack based on timing.
;
;Finally, below is an implementation of the complete encryption
;function in 8086 assembler, to replace the cipher_idea() function
;in PGP. It takes the same parameters as the function from PGP,
;and uses the c language calling conventions. I tested it using
;the debug features of the idea.c file in PGP. You will need to
;add segment/assume directives. This version uses no global data
;and should be reentrant.
;
;The handling of zero multipliers is outside the inner loop so
;that a short conditional jump can loop back to the beginning.
;Forward conditional jumps are usually not taken and backward
;jumps are usually taken, which is consistent with 586 branch
;prediction (or so I've heard). Stalls where the output of one
;instruction is needed for the next seem unavoidable.
;
;Last I heard, IDEA was patent pending. My code is up for grabs,
;although I would get a kick out being credited if you use it.
;On the other hand Colin's code is already tested and ready
;to assemble and link with PGP.

possible since we can only endianness-swap 4 bytes at a time which
precludes swapping the data. The use of the temp variable when the IV is
copied back in the _BIG_WORDS case is to eliminate multiple memory
accesses when the four bytes are extracted from ivLong[ n ], since many

The output has been subject to swaps of the form
0 1 -> 3 1 but the odd and even bits have been put into
2 3 2 0
different words. The main trick is to remember that
t=((l>>size)^r)&(mask);
r^=t;
l^=(t<<size);
can be used to swap and move bits between words.
So l = 0 1 2 3 r = 16 17 18 19
4 5 6 7 20 21 22 23
8 9 10 11 24 25 26 27
12 13 14 15 28 29 30 31
becomes (for size == 2 and mask == 0x3333)
t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19
6^20 7^21 -- -- 4 5 20 21 6 7 22 23
10^24 11^25 -- -- 8 9 24 25 10 11 24 25
14^28 15^29 -- -- 12 13 28 29 14 15 28 29
Thanks for hints from Richard Outerbridge - he told me IP&FP
could be done in 15 xor, 10 shifts and 5 ands.
When I finally started to think of the problem in 2D
I first got ~42 operations without xors. When I remembered
how to use xors :-) I got it to its final state.

; Simple RC4 implementation, Peter Gutmann, 21 September 1995.
; This code was written in about 30 minutes as a testbed for an asm.RC4. It
; uses a static data area as the key so it's not terribly practical as it
; stands. In addition, the RC4 algorithm leads to an almost solid block of
; pipeline stalls on anything >= '486, so I wouldn't recommend using it on
; anything except perhaps 8-bit microcontrollers and smart cards.

# Validation
The reconstructed sources were checked in two ways.
## 1. Header/API syntax check
`des.c`, `undes.c` and the common support compile syntactically against the
actual `crypt.h` from the supplied `cryptl99.zip`. There are no remaining
placeholder CRYPTLIB declarations.
## 2. Full CRYPTLIB round-trip on a modern compiler
For a behavioural sanity check, the supplied CRYPTLIB 0.99 source and libdes
3.14 source were compiled with GCC 14.2 together with the reconstruction.
A binary test file was then processed as:
```text
plain.bin -> des_v2 -> encrypted.bin -> undes_v2 -> roundtrip.bin
```
`plain.bin` and `roundtrip.bin` compare byte-for-byte equal.
The generated single-block encrypted file has the expected size:
```text
4 version
4 IV
256 password-check block
16384 encrypted data block
-----
16648 bytes total
```
The prefix begins with `75 27 00 00`, i.e. file version `0x00002775` in the
little-endian format used by the DOS executable.
A second test with an incorrect password exits with status 1 and prints the
same executable string:
`Password is not correct, no decryption possible`
## Scope of this validation
This confirms that the reconstructed control flow is internally consistent
with the supplied CRYPTLIB source. It does **not** prove that a modern GCC
build produces ciphertext byte-for-byte identical to the original Turbo C
build. The strongest compatibility test would be to decrypt an actual file
created by the 1998 `des.exe`, or run the original executable in a DOS
environment and compare outputs.
