How Does Digest Auth Work? Specifically, digest access authentication uses the HTTP protocol, applying MD5 cryptographic hashing and a nonce value to prevent replay attacks. Hash values are affixed to the person’s username and password before they are sent over the network, enabling the provider’s server to authenticate the person. What is nonce in HTTP?
What Is The Purpose Of A Challenge-response Mechanism? Challenge-response authentication uses a cryptographic protocol that allows to prove that the user knows the password without revealing the password itself. Using this method, the application first obtains a random challenge from the server. Why is challenge-response identification system used? Challenge-response identification improves upon simpler authentication protocols,
