  • Development
    The original specification of the algorithm was published in 1993 under the title Secure Hash Standard, FIPS PUB 180, by U.S. government standards agency NIST.
  • In Group: Cryptographic Techniques, Lead
    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.
