The Cryptokit library for Objective Caml provides a variety of
cryptographic primitives that can be used to implement cryptographic
protocols in security-sensitive applications. The primitives
provided include:
- Symmetric-key ciphers: AES, DES, Triple-DES, ARCfour,
in ECB, CBC, CFB and OFB modes.
- Public-key cryptography: RSA encryption, Diffie-Hellman key
agreement.
- Hash functions and MACs: SHA-1, MD5, and MACs based on
AES and DES.
- Random number generation.
- Encodings and compression: Base64, hexadecimal, Zlib compression.
Additional ciphers and hashes can easily be used in conjunction
with the library. In particular, basic mechanisms such as chaining
modes, output buffering, and padding are provided by generic classes
that can easily be composed with user-provided ciphers. More
generally, the library promotes a "Lego"-like style of constructing
and composing transformations over character streams.
Stegdetect is an automated tool for detecting steganographic content in
images. It is capable of detecting several different steganographic
methods to embed hidden information in JPEG images.

A bug was discovered in the key validation code. This bug causes keys
with more than one user ID to give all user IDs on the key the amount
of validity given to the most-valid key.

OpenCDK (Open Crypto Development Kit) provides basic parts
of the OpenPGP message format. The aim of the library is
*not* to replace any available OpenPGP version. There will be
no real support for key management (sign, revoke, alter
preferences, etc) and some other parts are only rudimentary
available. The main purpose is to handle and understand
OpenPGP packets and to use basic operations.

The libtasn1 library is part of GnuTLS and was developed for ASN1
(Abstract Syntax Notation One) structures management.

This is a general purpose cryptographic library based on the
code from GnuPG. It provides functions for all cryptograhic
building blocks: symmetric ciphers (AES, DES, Blowfish, CAST5,
Twofish, Arcfour), hash algorithms (MD4, MD5, RIPE-MD160, SHA-1,
TIGER-192), MACs (HMAC for all hash algorithms), public key
algorithms (RSA, ElGamal, DSA), large integer functions, random
numbers and a lot of supporting functions.
