Correct Answer: A
SHA was designed by NSA and published by NIST to be used with the Digital Signature Standard (DSS).
SHA was designed to be used in digital signatures and was developed when a more secure hashing algorithm was required for U.S. government applications.
SHA produces a 160-bit hash value, or message digest.
This is then inputted into an asymmetric algorithm, which computes the signature for a message. SHA is similar to MD4. It has some extra mathematical functions and produces a 160-bit hash instead of a 128-bit hash like MD5, which makes it more resistant to brute force attacks, including birthday attacks.
SHA was improved upon and renamed SHA-1. Recently, newer versions of this algorithm have been developed and released such as SHA2 which has the following hash length: SHA-256, SHA384, and SHA-512.
NOTE: Very recently SHA-3 has also been releasd but it is to new to be in the CBK.
The following answers are incorrect: RSA Diffie Hellman
Elliptic Curve Cryptography(ECC)
All of the choices above are examples of an Asymmetric algorithm
