LibTomCrypt 1.16

LibTomCrypt is a comprehensive, modular, and portable cryptographic toolkit.
LibTomCrypt is a comprehensive, modular, and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo- random number generators, public key cryptography, and a plethora of other routines. It has been designed from the ground up to be very simple to use. It has a modular and standard API that allows new ciphers, hashes, and PRNGs to be added or removed without change to the overall end application. It features functions for easy handling and a complete user manual which has many source snippet examples.

LibTomCrypt is free for all purposes under the public domain. This includes commercial use, redistribution and even branching.

Here are some key features of "LibTomCrypt":

· Public domain and open source.
· Written entirely in portable ISO C source (except for things like RNGs for natural reasons)
· Builds out of the box on virtually every box. All that is required is GCC for the source to build.
· Includes a 90+ page user manual in PDF format (with working examples in it)
· Block Ciphers
· Ciphers come with an ECB encrypt/decrypt, setkey and self-test interfaces.
· All ciphers have the same prototype which facilitates using multiple ciphers at runtime.
· Some of the ciphers are flexible in terms of code size and memory usage.
· Ciphers Supported.
· Blowfish
· XTEA
· RC5
· RC6

· CAST5
· Noekeon
· Skipjack
· Anubis (with optional tweak as proposed by the developers)
· Khazad
· Changing Modes
· Modes come with a start, encrypt/decrypt and set/get IV interfaces.
· Mode supported.
· ECB
· CBC
· OFB
· CFB
· CTR
· One-Way Hash Functions
· Hashes come with init, process, done and self-test interfaces.
· All hashes use the same prototypes for the interfaces.
· Hashes supported.
· MD2
· MD4
· MD5
· SHA-1
· SHA-224/256/384/512
· TIGER-192

· EAX Mode
· OCB Mode
· Pseudo-Random Number Generators
· Yarrow (based algorithm)
· RC4
· Support for /dev/random, /dev/urandom and the Win32 CSP RNG
· Fortuna
· SOBER-128
· Public Key Algorithms
· RSA (using PKCS #1 v2.1 and PKCS #1 v1.5)
· DH (using ElGamal signatures and simple DH encryption)
· ECC (over Z/pZ, ElGamal Signatures, simple DH style encryption)
· DSA (Users make their own groups)
· Other standards
· PKCS #1 (both v1.5 and v2.0 padding)
· PKCS #5
· ASN.1 DER for INTEGER types.

What's New in This Release:

· The ECC code was fixed, cleaned, and improved.
· GCM was fixed.
· UTF8 support was added to the ASN1 code.
· The documentation was improved.
· The published version of the manual is included.
