WebThe FNV1 hash comes in variants that return 32, 64, 128, 256, 512 and 1024 bit hashes. The FNV-1a algorithm is: hash = FNV_offset_basis for each octetOfData to be hashed hash = hash xor octetOfData hash = hash * FNV_prime return hash Where the constants FNV_offset_basis and FNV_prime depend on the return hash size you want: WebThere is one constructor method named for each type of hash.
