7.3. Taking Keys Into Use​

Key exchange ends by each side sending an SSH_MSG_NEWKEYS message. This message is sent with the old keys and algorithms. All messages sent after this message MUST use the new keys and algorithms.

When this message is received, the new keys and algorithms MUST be used for receiving.

The purpose of this message is to ensure that a party is able to respond with an SSH_MSG_DISCONNECT message that the other party can understand if something goes wrong with the key exchange.
