Question

Give differences between hash function and message authentication codes

Answer 1

hey mate,
hash function:- When sending encrypted data, SSL typically uses a cryptographic hash function to ensure data integrity. The hash function prevents Charlie from tampering with data that Alice sends to Bob.

message authentication:- messege authentication code or (MAC) is similar to a cryptographic hash, except that it is based on a secret key. When secret key information is included with the data that is processed by a cryptographic hash function, the resulting hash is known as an HMAC.

hope it help you!
