WinPT also supports an option called symmetric encryption, which does not use keys, but simply uses a passphrase to encrypt and decrypt messages. As long as the other party knows the passphrase, they can perform the decryption without a problem. Symmetric encryption is useful for one-shot encryption jobs -- for instance, if you're employing a disposable password that will never be used again (what's known in crypto circles as a "one-time pad.")
You can invoke WinPT through keyboard hotkeys, too. Instead of using the tray icon commands, you would set up the program to do an encrypt by pressing Alt+Shift in conjunction with a letter key. To configure this, right-click on the tray icon, select Preferences | WinPT, uncheck "Disable hotkeys," and configure the "Hotkey management" section with the keystrokes you want to use. (Other programs that perform hotkey trapping may interfere with this, so experiment with it.)
