We have now added the functions md5() and md5File() to the default expression handler. Md5 hashes are widely used by web services. The md5() and md5File() functions will thus make it easier to integrate.
md5( <string> ) -> <hash>
md5File( <filename> ) -> <hash>
md5( <string> ) -> <hash>
md5File( <filename> ) -> <hash>
