WebbSHA-1 was the original secure hashing algorithm, returning a 160-bit hash digest after hashing. Someone may wonder, can SHA-2 be cracked like SHA-1? The answer is yes. Due to the short length of the hash digest, SHA-1 is more easily brute forced than SHA-2, but SHA-2 can still be brute forced. Webb10 apr. 2024 · SHA-1 and SHA-2 differ in several ways; mainly, SHA-2 produces 224- or 256-sized digests, whereas SHA-1 produces a 160-bit digest; SHA-2 can also have block sizes that contain 1024 bits, or 512 bits, like SHA-1.
