- * Therefore, it is important that we reject connections from
- * unauthorized remote agents.
- *
- * <p>
- * We do this by computing HMAC of the agent name.
- * This code is sent to the agent inside the {@code .jnlp} file
- * (this file itself is protected by HTTP form-based authentication that
- * we use everywhere else in Jenkins), and the agent sends this
- * token back when it connects to the master.
- * Unauthorized agents can't access the protected {@code .jnlp} file,
- * so it can't impersonate a valid agent.
- *
- * <p>
- * We don't want to force the inbound agents to be restarted
- * whenever the server restarts, so right now this secret master key
- * is generated once and used forever, which makes this whole scheme
- * less secure.
