Accept any string and print its SHA256 hash value using Secure Hash Algorithm 2 (SHA-2) algorithum. It consists of six hashing algorithms from that here i used SHA-256 algorithm,
SHA-256 is a -bit ( byte) hashing algorithm which can calculate a hash code for an input of up to bits. It undergoes rounds of hashing and calculates a hash code that is a -digit hexadecimal number.
