WebSHA-1 uses an internal compression function (that's the traditional term); it also has a running state consisting of five 32-bit words. The compression function takes as input two values of 160 and 512 bits, respectively, and outputs 160 bits. The processing goes like this: WebDec 20, 2024 · SHA 512/256 Hash values are generated using a different set of cryptographic hash algorithms in each member of the family. The hash value in SHA 256 consists of 256 bits (equal to 32 bytes). Six unique hash functions were created by varying the number of rounds, shift amounts, and additive constants (more on that in a moment).
