What is SHA-1 (Secure Hash Algorithm 1)?

A
SHA-1 (Secure Hash Algorithm 1) is a hash function,
developed by the US National Security Agency (NSA)
and published by the National Institute of Standards and Technology (NIST).
SHA-1 or Secure Hash Algorithm 1 is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value. This hash value is known as a message digest. This message digest is usually then rendered as a hexadecimal number which is 40 digits long.
SHA-1 is now considered insecure since 2005 and it has been replaced by SHA-2 (Secure Hash Algorithm 1) hash functions: SHA-256 and SHA-512.
