I pgp sign my tag operation request emails using my own computer in the normal way. If I go away and want to send operation requests and I take a copy of my pgp keys with me where do I upload the keys to on the public computer I would use to be able to then sign a yahoo email operation request before sending it to the automaton? I've tried it on a local public computer but couldn't work out how to manage the procedure correctly. I don't want to take a laptop with me with the keys already installed. Any ideas?
