A library of cryptographic hashing algorithms

Please see LICENSE file for license.
IMPORTANT:
This library was not written for actual use.
Rather, it was meant for educational purposes,
so if you choose to use it in a real setting
where secrecy is required, do so at your own risk.
People who use this library to learn about the
algorithms can easily add a few std::couts to
see the internal data.
Hashes:
Microsoft's LM Hash
MD2
MD4
MD5
RIPEMD-128
RIPEMD-160
SHA-1
SHA-224
SHA-256
SHA-384
SHA-512
SHA-3 (independent Keccak implementation active, but not sure on correctness)
MACs
HMAC
POLY1305AES
Build:
make (creates the object files and libHashes.a)
or
g++ -std=c++11 main.cpp common/*.cpp Encryptions/*.cpp Hashes/*.cpp -lgmpxx -lgmp
or some equivalent
Test code and its makefile are included in the test folder.
Usage:
Ex:
SHA1 instance(data to hash in ASCII)
To get digest:
instance.digest()
To get hex string of digest:
instance.hexdigest()
To update:
instance.update(more data)
Notes:
The GNU Multiple Precision Arithmetic Library (GMP) is needed
for POly1305-Aes (gmp.org, sudo apt-get install libdev-gmp, or
equivalent).
My Encryptions library is needed for this library. It is included
in this project.
The format was inspired by the Python 2.7 hashlib module
Hashes.h provides a quick test to check that the algorithms are correct.
