Includes hash lengths of 256 and 512

WebCurrently, the gold standard in the industry is any hash in the SHA-2 family of hashes of bit-length 256 or greater. This includes SHA-256, SHA-384, and SHA-512. These hashing algorithms are recommended via the NIST in FIPS PUB 180-2 (which has since been superseded by FIPS PUB 180-4 but retains the recommendation). WebMar 8, 2024 · SHA-512 and the other SHA2 variants (SHA-256, SHA-384, etc.) have collisions. We know this by applying a very simple mathematical theorem, the pigeonhole principle. A SHA-512 hash is a 64-byte string. There are strictly more strings of 0 through 64 bytes than strings of exactly 64 bytes.
