md5 is a cryptographic hash function. It's designed to prevent you from retrieving the orginal password. – Håken Lid Jun 08 '16 at 08:55

Just google the hash. – AUsr19532 Jun 08 '16 at 09:06

No way (almost). This is what md5 is designed for (although it has some weakness, better in this matter are the algorithms of the sha family, and in there sha2 and sha3). The basic idea of any cryptograhpic hash is to create results such that for different inputs the hash value differs with high probability, but reconstructing the original input from the hash is as difficult as possible.
There are collision attacks known to md5, but you cannot be sure to get the original password back, if you succeed, only an equivalent one in the sense that both produce the same hash. I do not assume that you want to try doing so, though...
