Welcome to SHA1 Online Computing
SHA1
SHA-1 (English: Secure Hash Algorithm 1) is a cryptographic hash function designed by the US National Security Agency and developed by the US National Institute of Standards and Technology (NIST) Published as Federal Data Processing Standard (FIPS) [2]. SHA-1 can generate a 160-bit (20-byte) hash value called a message digest, which is usually represented as 40 hex number.
