hash

This module provides a framework for cryptographic and non-cryptographic encryption.

Examples,

%> import hash
%> 
%> hash.md5('Hello, World')
'82bb413746aee42f89dea2b59614f9ef'
%> 
%> hash.sha256('Hello, World')
'03675ac53ff9cd1535ccc7dfcdfa2c458c5218371f418dc136f2d19ac1fbe8a5'
%> 
%> hash.siphash('mykey', 'Hello, World')
'd8e830a590c92b4c'
%> 
%> hash.hmac_sha256('mykey', 'Hello, World')
'61035d3d2119ffdfd710913bf4161d5fba1c2d9431f7de7ef398d359eb1d2481'
%> 
%> hash.hmac_sha256(bytes([10, 11, 12]), 'My secure text!')
