Well, the whole point here is the interface implementation. A consistent
user experience. As others have pointed out we already have *many*
different lower level encryption libraries, backends, agents, key and
certificate caching solutions etc... These do a great job in their
What we don't have is a consintent UI and user experience. This is what
this API proposes to address.
The implementor of this API will obviously use the underlying libraries
and code already available. This API simply provides the point where
high level consumers of public key encryption can, using this proposed
API, hook into whatever implementation is available on the system.
Hence a DBUS service.

Yes, that's a good point. For high security user interaction, gpg-agent
and others already have this functionality. The implementor of this API
would call out to GPG and on a properly implemented system, gpg would
prompt via gpg-agent and if desired this could occur on a different
terminal. In any case, this doesn't have much to do with the proposed API.

Agreed, although as others have pointed out, almost anything can be
spoofed given a compromised system. But yes, the seperate process does
allow us to do some security conscious things that would be difficult
given a library.

In any case, seahorse is going to start working in this direction on
it's own for now. We'll see how it goes and then see if the some of the
various email clients are interested in adoption.
Hopefully the API idea will either prove or disprove itself, given time
and the collaboration of everyone involved.
