What Is SHA-256 and How To Calculate In Python, PHP, JavaScript, Go, Java, PowerShell Programming Languages?

Hash algorithms are the heart of the cryptography and security. SHA-256 is a Secure Hash Algorithm which will generate an output hash value in 256 bit. SHA-256 is designed by the National Security Agency  (NSA). SHA-256 is one of the cryptographic hash functions. SHA-256 is also named one-way function where the generated hash value cannot be reversed theoretically. This makes SHA-256 very useful for password validation, challenge hash authentication, anti-tamper,...
