Can I do this with your APIs?

I want to store my clients' and my public keys in a database table in a clob field in base64 format, as exported from the GPG keychain.

My goal is to avoid creating a GPG keychain on the servers where the WAR app will run and having to access the chain in the file system.

What I need to know is:

Given an input steam from said string/clob, can I instantiate a PGPPublicKey with just this information? And then given a newly created virtual PGPPublicKeyRingCollection containing just one key can be used in encrypting and decrypting.

Can anyone point me at specific examples or a list of Classes I should look at using?

Thanks in advance!
