Introduction Here in this article I am explaining that how to implement a login form with the help of SHA-256 Cryptography algorithm. SHA-256 is a standard method for generating digital signature. It is a one way algorithm. The SHA256 algorithm is known as one way encryption, hash or checksum, digest and digital signature algorithm. The SHA core provide implementation of cryptographic Hashes SHA-1, SHA-2, SHA-256, SHA-512. Getting Started
