3. Protocol Overview

このページは RFC 9987 の該当節を要約し, SSH agent protocol の番号, メッセージ名, セキュリティ要件を保持します.

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.
