Frequently Asked Questions about MD5 Encryption

What is a MD5 Hash?

MD5 is a hash function that produces a unique* 128-bit hash value.

Who designed the MD5 Hash Algorithm?

The MD5 hash algorithm was designed in 1991 by Ronald Rivest to replace MD4.
The algorithm was officially published in April 1992. The specifics of the MD5 hash algorithm are specified in RFC 1321.

*In 1996, Hans Dobbertin announced that a collision was possible. This later led most cryptographers to move to SHA-1.
