conceptual questions

[Thomas Stover <thomas wsinnovations com>]

While browsing around to see if something exists before I start yet 
another thing to maintain, I found seahorse. I'm looking for something 
that holds keys (or even raw passwords) in a background process 
volatilely. Then client applications "set" and "get" keys to it. Just 
like ssh-agent except having some means of actually getting the keys 
and/or passwords. Or at least be able to send it some arbitrary data for 
it to decrypt and securely pass back to a client. Is something like this 
part of seahorse? Any one know of something that is? A reusable solution 
to this seems to obvious a need for somebody not to have already solved it.
