Ada-Crypto-Library

The libadacrypt-dev is a crypto library for Ada with a nice API. It is written for the i386 and x86_64 hardware architecture and supports AES, Twofish, 3DES, Serpent SHA-1/256/384/512, DSA, OAEP-RSA, HMAC, CMAC, SIV, OCB, Nonces, Elliptic Curves. etc. It also contains regression tests consisting of over 400 tests. Dependencies: make and gnat-4.9.

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
    • Key Derivation Functions: PBKDF2, scrypt, and SHA-512crypt
  • 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-3.7.1 based Test suite (over 400 tests, about 90% line coverage)

Getting started

Prerequisites

  • GNAT-4.8 (recommended version: 4.9)
  • GNU Make (recommended version: 4)
  • gcov (recommended version: 4.8.3; optional for testing only)
  • lcov (recommended version: 1.10; 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

AUNIT support

This crypto library assumes that the aunit source PATH is /usr/share/ada/adainclude/aunit/. If needed, you should change this path in the project file acltest.gpr. In additon, you can cahnge the PATH in test/Makefile.
