"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. " - Simplified sha-1
