In 1992, he improved on MD4 and developed another hash function: MD5. In 1993, the National Security Agency published a hash function very similar to MD5, called the Secure Hash Algorithm (SHA).

Hash algorithms are used by government agencies and businesses worldwide to make online transactions secure, store passwords and verify digital files and signatures.
