WebSHA-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.

WebIf you only need to support 64 bit CPUs and most messages are 120 bytes or longer, then SHA512 will be faster than SHA256. If you need to support a mixture of 32 and 64 bit CPUs or if most messages are 55 bytes or shorter, then SHA256 will be faster than SHA512. – kasperd. Mar 27, 2016 at 15:05.
