Description: The object used to change any given user's Privacy Key using a Diffie-Hellman key exchange.
The right-most n bits of the shared secret 'sk', where 'n' is the number of bits required for the protocol defined by usmUserPrivProtocol, are installed as the operational privacy key for this row after a successful SET.
What is usmDHUserPrivKeyChange?
A control object used to change a specified SNMPv3 user's privacy (encryption) key via a Diffie-Hellman key exchange. Admins use it to rotate another user's encryption key securely, deriving the new key from a shared secret rather than transmitting it in the clear. Rotating the privacy key for a service account before decommissioning shared credentials would involve setting this object with the new DH exchange value.
