/** <module> MD5 hashes
Compute MD5 hashes from a Prolog string. This library provides a
lightweight alternative to the general secure hash interface provided by
library(crypto) from the `ssl` package.
@see library(sha), library(hash_stream) and library(crypto).

%! md5_hash(+Data, -Hash, +Options) is det.
%
% Hash is the MD5 hash of Data, The conversion is controlled by
% Options:
%
% * encoding(+Encoding)
% If Data is a sequence of character _codes_, this must be
% translated into a sequence of _bytes_, because that is what
% the hashing requires. The default encoding is =utf8=. The
% other meaningful value is =octet=, claiming that Data contains
% raw bytes.
%
% @arg Data is either an atom, string, code-list or char-list.
% @arg Hash is an atom holding 32 characters, representing the
% hash in hexadecimal notation
