Question: A user is instructed by a boss to find a better method to secure passwords in transit. the user has researched several means to do so and has settled on using hmac. what are the key elements needed to implement hmac?
To implement HMAC (Hash-based Message Authentication Code), the key elements needed are a cryptographic hash function (such as SHA-256), a secret key that is shared between the sender and receiver, and a method for combining the hash function and secret key to generate a message authentication code. The HMAC algorithm involves the application of the hash function to both the secret key and the message being transmitted, followed by a combination of the two hash results using a specific algorithm. This produces a unique message authentication code that can be transmitted alongside the original message to ensure its integrity and authenticity during transit.
