getMD5Hex is a function commonly found in utility libraries (such as Apache Commons Codec) that calculates the MD5 hash of data (like a string or file) and returns the result as a 32-character hexadecimal string 

Example:

var sname = 'Joe Bloggs';

var value = new GlideDigest().getMD5Hex(sname.toLowerCase());

gs.info ('result==='+value);
