The sha-1 algorithm (Secure Hash Algorithm 1), designed by the United States National Security Agency, produces a 160-bit (20-byte) hash value which is typically displayed as a 40 digit long hexadecimal number. The sha1 hash as well as md5 were designed to make it impossible to reverse engineer the original string. Sha1 is a bit better than md5, however mainly due to the fast nature of this hashing algorithm it's no longer recommended to use this hash technique with sensitive data such as passwords.
