WebMar 2, 2024 · A sha256 is 256 bits long -- as its name indicates. 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. And the demo : 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.
