SHA-1
SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function designed by the National Security Agency and published as a Federal Data Processing Standard (FIPS) by the National Institute of Standards and Technology (NIST) [2]. SHA-1 can generate a 160-bit (20-byte) hash value called a message digest, which is usually represented as 40 hexadecimal digits.
