CryptoStreams 3.0

New major release!

Features:

• 6 new PRNG sources
• 16 new lighweight block ciphers
• Published Master's thesis my Michal Hajas on PRNG and Lightweight crypto: see here

Minor changes:

• Newly we test test coverage + added many test vectors for many implemented functions
• Added SHA3 version of Keccak (slightly different constants)
• Correctly passing hash bitsize in constructors

CryptoStreams 2.3

Fixes of 3 bugs:

• Parsing of config file: #85
• Column stream bit order: #86
• Rabbit stream cipher was implemented incorrectly: #87

Cryptostreams 2.2

Major changes:

• Added stream piping to construct more complex streams
  • Streams like rho_stream, random_plaintext_ciphertext_stream removed, as they can be fully constructed using piping.

Minor changes:

• RC4 generation fixed -- issue with state re-initialization

Cryptostreams 2.1

Minor fixes from 2.0 release:

• Fixed round-reduction of XTEA and MICKEY
• Disabled CryptMT as it fails to link in release mode on Debian
• Removed GPL code (with inactive CAESAR as well) and change licence to MIT
• Added contributing notes
• New generation strategy: decryption mode for block ciphers

CryptoStreams 2.0

Incorporate all changes in ph4r05's and rozsa117's branches. And release all current features.

Main news:

• Known answer tests (test vectors)
• Refactoring:
  • Generalisation of SHA-3 -> hash and eSTREAM -> stream_ciphers
• Whole lotta new cryptoprimitives and streams
  • AES candidates: Blowfish, Mars, Serpent, RC6, and Twofish
  • Simon and Speck (NSA low power block ciphers)
  • Block ciphers from TLS: ARIA, Camellia, CAST, IDEA, and SEED
  • Other block ciphers: Gost, Kasumi, MISTY1, Kuznyechik, NOEKEON, SHACAL-2, and XTEA
  • Hash functions: SHA-1, SHA256, MD5, Gost, Ripemd160, Tiger, and Whirlpool
  • Stream ciphers: Chacha, RC4 moved to right class
  • Streams: Low hamming weight counter, random plaintext and corresponding ciphertext output together, Rho stream (takes its output as input for next call), and others
• Significant (backward incompatible) config changes (kebab-case changed do snake_case).
• New API
• Static and dynamic analysis

We have to celebrate this all, and the new name CryptoStreams as well :).

Generator v1.0

First release of the generator tool

• Supported function:

• eSTREAM finalists (Grain, HC-128, Rabbit, Salsa20, SOSEMANUK)
• SHA-3 finalists (BLAKE, Grostl, JH, Keccak, MD6, Skein)
• Other well-known functions: AES, DES, 3-DES, RC4.
• And many others that were not verified yet.

• Stream transformers and sources:

• true and false bits streams
• PRNG streams
• counter, Strict avalanche criterion streams
• postprocessing: bit selection, transposition

Provided Python script can run the basic setup for functions mentioned above. The script is parametrised by cmd arguments. Example for 1 MB file from 3 rounds AES:

python3 ./generator.py -f AES -r 3 -d 1000000
