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 a fairly 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.

LibTomCrypt 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 easy to use functions 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

SAFER+

Rijndael (aka AES)

Twofish

SAFER (K64, SK64, K128, SK128)

RC2

DES, 3DES

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

RIPE-MD 128/160

WHIRLPOOL

Message Authentication

FIPS-198 HMAC (supports all hashes)

FIPS pending OMAC1 (supports all ciphers)

PMAC Authentication

Message Encrypt+Authenticate Modes

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:

A couple of bug fixes (notably the prime generation function p_prime_random_prime_ex())

Added cool "multi" functions (see demos/multi.c)
