Multiple Choice

Which document is known as the Secure Hash Standard?

Explanation:
The Secure Hash Standard is the official specification that defines hash functions used to produce a fixed-size digest from input data. This standard is published as FIPS 180-2, which describes the SHA family of cryptographic hash algorithms. The other documents refer to different areas—for example, FIPS 140-2 covers security requirements for cryptographic modules, and FIPS 186-2 defines the Digital Signature Algorithm—so they aren’t the Secure Hash Standard.
