hi aycanirican,

the output is the packed version of the md5 which is correct. the pack hash is usually the one getting sent, stored or passed around as it is shorter. To turn it in an hexadecimal version, which is usually the one displayed, you can use the same kind of function as the hexalise function in Tests.hs
