Userfriendly strings

Hi Jacob!

thanks for your work!

I wanted to suggest to use more user friendly strings. For example, I think it would be nice to not simply use the word "key" in "generate keys", but to use "key pair" instead. This would be making it clear that you generate a private and a public key, for example. For users new to OpenPGP/GPG such wording might be more appropriate and understandable.

What do you think? Cheers, Ulrike
