WebThe NIST has since published three variants of SHA-1 that produce larger hashes: SHA-256, SHA-384, and SHA-512. Although with the larger hash sizes these algorithms should be more secure, they have not undergone as much analysis as SHA-1. Nevertheless, the hash length is important to protect from brute-force and birthday attacks. Hacking the Code … SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of si…

Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar (64), or even a char (64), as the length is always the same, not varying at all.
