Explanation

Digest Authentication secures credentials by using a server-generated nonce (a randomly generated number) in combination with the user's credentials (username and password) to form a response hash. This nonce ensures that the hash is unique for each authentication session, protecting against replay attacks. The server validates the hash to confirm the user's identity without transmitting the actual password.
