WebMar 26, 2024 · SHA-0 is a single 160-bit hash function aimed at 80-bit collision security (and now completely broken), based on the relatively new and fast design of MD4 in 1990. In 1995, NIST quietly withdrew FIPS 180 and replaced it by FIPS 180-1 defining SHA-1 , which differs from SHA-0 by the inclusion of a single one-bit rotation. WebSHA-0 (the first published version of SHA since then replaced by SHA-1) and SHA-1 produce a message digest of 160 bits, SHA-224 of 224 bits, SHA-256 of 256 bits, SHA-384 of 384 bits, and SHA-512 of 512 bits, respectively. All six functions start by padding the message according to the so-called Merkle-Damgård strengthening technique.
