actually the correct answer is:
it is mathematically impossible to get the original password back once it is encrypted.

that's because md5 is a hasfunction (a so called fingerprint) and not a real encryption function.

there can be two different passwords which have the same hash, so as said mathematically impossible to get the original pw back (but it's technically possible to get a pw which will work as the original one, but that's a very complicated process and takes a long time to generate)
