1. Introduction

Diese Seite fasst den entsprechenden Abschnitt von RFC 9987 zusammen und bewahrt Nummern, Nachrichtennamen und Sicherheitsanforderungen des SSH-Agent-Protokolls.

Secure Shell (SSH) [RFC4251] provides secure remote connections and login over untrusted networks. It supports public key authentication and other authentication mechanisms.

This document specifies a protocol for interacting with a key management component, usually called an agent, that holds private keys. SSH clients, and possibly SSH servers, can invoke the agent to perform operations using public and private keys held by the agent.

Keeping keys in an agent avoids repeatedly loading and unwrapping private keys, supports optional forwarding across an SSH connection, and can reduce attack surface by isolating key handling in a smaller component.
