I've used SSH Agent (the Mac GUI app) for many years, and combined with shortcuts (now "functions" in ~/bash_profile, like function gent { ssh -2C root@192.168.0.101; } ) the process has made it very easy and fast to login very securely to my various servers. Agent, however, recently lost the ability to grab my passphrases from the keychain, so every few weeks when I reboot I've needed to type them in to startup the agent again, and finally got fed up.

This looks like it will do very nicely, as well as adding some extra security tweaks to my process. Only hitch was digging far enough into the developer site to find the bit about going to prefs, Environment tab, and enabling the checkbox, then logging out and back in to get it to work. Oh, also that when I turned off display in the dock, it removed any display at all, anywhere, and lost the ability to reset or interact with the application at all. Had to delete the prefs file and reboot to see or talk to SSH Keychain again. That done, though, it is working very nicely now!! Thanks and kudos!
