The MD5 hash algorithm is a cryptographic hash function, not an encryption method. A cryptographic hash function converts a message of variable length to a fixed size of 'hash,' usually done to check the integrity and authenticity of the original message, and not transmit the message itself in a unreadable encrypted way. The message is also sent ALONG with the hash, usually to ensure that the original message has not been altered en route. Thus it does not have enough information to actually retrieve the message itself. (although it can if the size of the message is the size of the hash, it is never the case.) Decrypting the MD5 hash string will not yield the information that was used for its creation anyways.
