Hmmmm. Is this 'openkey' a public key? Is it yours or somebody elses? If you're using winGPG like most people, then you copy paste the encrypted message into your gpg clipboad and click decrypt. Of course, they will need your public key to send an encrypted message in the first place.I'm not really getting how this is based upon what email program you're using or whether you're using webmail or not. Some programs have PGP functionality, others don't. It's a feature, but if you're using an independent PGP program it's not relevant.
