Hashilib module and HMAC module

For cryptographic related operations, the 3.x replaces the MD5 module and the SHA module, mainly providing the SHA1,SHA224,SHA256,SHA384,SHA512,MD5 algorithm (SHA512 the most complex and safest)

>>>ImportHashlib>>> m =hashlib.md5 () # Other encryption algorithms in the same vein>>> M.update ('666')>>>m.hexdigest () # 16 binary format Hash'Fae0b27c451c728867a567e8c1bb4e53'>>> M.update ('888')>>>m.hexdigest ()'75e266f182b4fa3625d4a4f4f779af54'>>> m_new =hashlib.md5 ()>>> M_new.update ('666888')>>>m_new.hexdigest ()'75e266f182b4fa3625d4a4f4f779af54'

The HMAC module internally creates key and content for us to process and then encrypt

>>> h = hmac.new (b'Where can I go a little later', b'go to the hospital')>>> h.hexdigest ()'8017d0aa2a051905ed8f821c3e2bdce5  '
