Welcome to the Ada Crypto Library (ACL) aka libadacrypt

This library is an ongoing project that provides the Ada community to strong cryptography primitives and schemes, focused to ensure data confidentiality and data integrity.

Implemented Features

  • Symmetric Cryptography
    • Blockciphers: AES, Twofish, 3DES, Serpent
    • Modes of Operation : BPS, CFB, Ctr, OFB
    • Tweakable Blockcipher Modes: CMT, XT
    • Hash functions: SHA-1 (broken), SHA-256, (SHA-384), SHA-512, Whirlpool
    • MACs: RMAC, HMAC, CMAC
    • Authenticated Encryption schemes: OCB, SIV and McOE
  • Big (unsigned) number library
    • Primary cyclic group arithmetic (Z_p)
    • Binary Field arithmetic support.
    • Elliptic Curve arithmetic
      • Supersingular Elliptic Curves Over Binary Fields (SS-BF)
      • Non-Supersingular Elliptic Curves Over Binary Fields (NSS-BF)
      • Elliptic Curves Over Z_p (EC-Z_P)
  • Asymmetric Cryptography
    • Probabilistic primality testing
    • DSA signature scheme
    • OEAP-RSA
    • ECDSA, ECDH
  • Nonce Generator Support: Random, Counter, Mixed
  • AUnit-3.4 based Test suite

Getting started

Prerequisites

  • GNAT-4.6
  • GNU Make 3.81 or newer
  • gcov 4.7.1 or newer (optional for testing only)
  • lcov 1.9 or newer (optional for testing only)

To build and test:

make
make acltest
cd test  
./test-tests

To generate LCOV code coverage report (location: test/coverage/):

make gcov
cd test  
./test-tests
make lcov

To build the PDF documentation (location: doc/):

make docu
