WebOct 10, 2024 · HMAC helps authenticate a message that one device sends to another. HMAC is like a cyclic redundancy check or CRC with a few differences. The secret key is configured on both devices, so it is ‘known’. The secret key is never transmitted across the unsecure medium. The message is sent in the clear so it is known by both devices. WebTSIG uses shared secret keys and one-way hashing to provide a cryptographically secure means of authenticating each endpoint of a connection as being allowed to make or respond to a DNS update. ...
