WebSHA-1: This is the second version of the Secure Hash Algorithm standard, SHA-0 being the first. SHA-1 creates 160-bit outputs. SHA-1 is one of the main algorithms that began to replace MD5, after vulnerabilities were found. SHA-1 gained widespread use and acceptance. SHA-1 was actually designated as a FIPS 140 compliant hashing algorithm. WebTherefore, each digit is a hex digit (0-15 or 0-F) and represents four bits, not eight. Taking that further, one byte or eight bits are represented by two hex digits, e.g. b' 1111 1111 ' = 0xFF = 255. MD5 hashes are 128 bits in length and generally represented by 32 hex digits.
