SHA256 a pièces de l'algorithme

SHA-256 is an algorithm developed by the National Security Agency. It was created to generate almost unique 32-byte signatures for texts. SHA-256 is a one-way cryptographic function because it is impossible to decrypt it and get the source text back. The algorithm was designed to improve the speed of computing, hence it is better not to use it to store encrypted passwords. Like any other hash functions, it is always at risk of brute-force attacks.
