3. Protocol Overview

Cette page resume la section correspondante du RFC 9987 et conserve les numeros, noms de messages et exigences de securite du protocole agent SSH.

The agent protocol is a packetised request-response protocol driven solely by the client. A client sends requests to an agent, and the agent sends replies in response and in order. The agent never sends messages except as a response to a client request.

Requests include loading keys into an agent, removing keys, listing keys, and performing signature operations using previously loaded keys. Agents MAY implement only a subset of key types and MAY refuse operations in particular contexts. Clients SHOULD fail gracefully when operations are refused.
