The SHA-256 algorithm is one flavor of SHA-2 (Secure Hash Algorithm 2),
which was created by the National Security Agency in 2001 as a successor to SHA-1
where SHA stands for Secure Hash Algorithm. SHA256 algorithm generates an almost-unique,
fixed size 256-bit (32-byte) hash. Hash is so called a one way function

h = sha256()
h.update(b'python1990K00L')
hash = h.hexdigest()
