In cryptography, SHA-1 (Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard. The algorithm has been cryptographically broken but is still widely used. In the first release in 2003, many Japanese ciphers were selected for the "e-Government Recommended Ciphers List": CIPHERUNICORN-E (NEC), Hierocrypt-L1 (Toshiba), and MISTY1 (Mitsubishi Electric) as 64 bit block ciphers, Camellia (Nippon Telegraph and Telephone, Mitsubishi Electric), CIPHERUNICORN-A (NEC), Hierocrypt-3 (Toshiba), and SC2000 (Fujitsu) as 128 bit block ciphers, and finally MUGI and MULTI-S01 (Hitachi) as stream ciphers.
