    B: MD5 can be used to locate the data which has changed. The Message Digest Algorithm (MD) creates a hash value and uses a one-way hash.
    The hash value is used to help maintain integrity. There are several versions of MD; the most common are MD5, MD4, and MD2.

    F: A common method of verifying integrity involves adding a message authentication code (MAC) to the message. HMAC (Hash-Based Message Authentication Code) uses a hashing algorithm along with a symmetric key.
