Available Hashing Algorithms

suggest change

hashlib.new requires the name of an algorithm when you call it to produce a generator. To find out what algorithms are available in the current Python interpreter, use hashlib.algorithms_available: 

import hashlib
hashlib.algorithms_available
# ==> {'sha256', 'DSA-SHA', 'SHA512', 'SHA224', 'dsaWithSHA', 'SHA', 'RIPEMD160', 'ecdsa-with-SHA1', 'sha1', 'SHA384', 'md5', 'SHA1', 'MD5', 'MD4', 'SHA256', 'sha384', 'md4', 'ripemd160', 'sha224', 'sha512', 'DSA', 'dsaEncryption', 'sha', 'whirlpool'}

The returned list will vary according to platform and interpreter; make sure you check your algorithm is available.

There are also some algorithms that are guaranteed to be available on all platforms and interpreters, which are available using hashlib.algorithms_guaranteed: 

hashlib.algorithms_guaranteed
# ==> {'sha256', 'sha384', 'sha1', 'sha224', 'md5', 'sha512'}
