[Python-Dev] New hash algorithms: SHA3, SHAKE, BLAKE2, truncated SHA512

Hi everybody, I have three hashing-related patches for Python 3.6 that are waiting for review. Altogether the three patches add ten new hash algorithms to the hashlib module: SHA3 (224, 256, 384, 512), SHAKE (SHA3 XOF 128, 256), BLAKE2 (blake2b, blake2s) and truncated SHA512 (224, 256). SHA-3 / SHAKE: https://bugs.python.org/issue16113 BLAKE2: https://bugs.python.org/issue26798 SHA512/224 / SHA512/256: https://bugs.python.org/issue26834 I like to push the patches during the sprints at PyCon. Please assist with reviews. Regards, Christian
