keychain

Re-use ssh-agent and/or gpg-agent between logins. More information: http://funtoo.org/Keychain.

• Check for a running ssh-agent, and start one if needed:
  keychain
• Also check for gpg-agent:
  keychain --agents "{{gpg,ssh}}"
• List signatures of all active keys:
  keychain --list
• List fingerprints of all active keys:
  keychain --list-fp
• Add a timeout for identities added to the agent, in minutes:
  keychain --timeout {{minutes}}
