Various cryptographic functions

The implemenation is supposed to be reasonably portable, incl. little endian and big endian systems, and reasonably fast.

Hashes

MD5 / RFC 1321
SHA1 / RFC 6234
SHA224 / RFC 6234
SHA256 / RFC 6234
SHA384 / RFC 6234
SHA512 / RFC 6234

HMAC

RFC 2104 / 6234

KDF

HKDF / RFC 5869 / 6234
PBKDF2 / RFC 2898 / 6070

Compatiblity

The code is C++11 code without any external dependencies.

Test Matrix

All algorithms will be tested by issueing make check, which happens to be the default target. The test will by default hash all hash* files (aka. the source and binaries) plus somme vectors in test-vectorsand compare the output against what the Python hashlib produces.

Passing tests:

Debian lenny x86_64 le, gcc-4.7
Debian wheezy mips/manta be, gcc-4.7
OSX 10.9/Darwin x86_64 le, clang-apple-5.1
OSX 10.9/Darwin i686 le, clang-apple-5.1
OSX 10.9/Darwin x86_64 le, gcc-4.8
OSX 10.9/Darwin i686 le, gcc-4.8
Windows x86_64-w64-mingw32 gcc-4.8.3
Windows WIN32 MSVC12u2 (create your own .sln)
Windows WIN64 MSVC12u2 (create your own .sln)

Status

This stuff is probably OK, and it has tests. Then again, it was not really peer reviewed...

As for performance: It is pretty much on par with other implementation, incl. the ones found in OpenSSL and/or Apple Common Crypto. It is not meant to be the most performant implementation on earth, though.
