Question: using ssh-agent as "protected memory" storage.

Hello,

Sorry to bother you all but I have already done a lot of research online
and haven't come to a satisfactory answer.

**** All I want, is to be able to store a small piece of data in
"protected memory", and then retrieve it again later. ****

I am already doing some pretty tricked-out stuff to store this data in
my own RAM, but that's not good enough -- I'd prefer to use some sort of
"standard" protected memory, versus trying to do it myself.

On Windows there is a function called "VirtualProtect" which does this,
and I thought perhaps ssh-agent might be able to provide the same
functionality on UNIX.

Is this possible? If not, what is the best way to go about doing such a
thing?

Alternately, is it possible to use ssh-agent for encrypting/decrypting
data using a key stored inside ssh-agent?  Because this would also solve
my problem. Does libssh2 allow me to encrypt/decrypt using the
identities, similar to how it allows me to authenticate using the
identities?
