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 40 digits long hexadecimal number. Sha1 hash as well as md5 were designed to make 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 techniques with sensive data such as passwords.
