SHA-1 is the most commonly used SHA algorithm, and produces a ______-byte hash value(size).
SHA-1 is the most commonly used SHA algorithm, and produces a ______-byte hash value(size).
SHA-1 produces a 20-byte (160-bit) hash value. Each byte contains 8 bits, and since SHA-1 generates a 160-bit hash, this equates to 20 bytes. It is well-known in cryptographic practices and standard documentation.
