Hi,

Let me try to elaborate.  First off let me preface this by stating I'm
fairly new to WSS4J (i.e. been using it for only 3 weeks), however I've
managed to make most combinations of Signature/Encryption to work (in
both directions).  That said, I'm not intricately familiar with the
source base as many of you are probably, and thus can't speak for the
feasibility of any of what I'm proposing so bear with me :).

One thing that I think many would find useful is the ability to use a
CallBack class to retrieve the key associated with a key name in
verifying or signing messages.  i.e. instead of going to a keystore file
to retrieve the key, you can retrieve the key from an alternate source
(e.g. database table).  Retrieving keys in this manner would allow a lot
of flexibility for key management I think.

Now maybe I'm misinterpreting the docs regarding the
ENC_CALLBACK_CLASS/ENC_CALLBACK_REF feature, but I understood these
features to do something along those lines (e.g. allow you to retrieve
the encryption/decryption keys from a place of your choosing vs. the
keystore file).

What do you guys think?  Ultimately my goal would be to have a method of
managing the keys on the web service end with a nice web interface: i.e.
customers submitting their public signature/encryption keys on the fly,
or conversely downloading the servers public signature/encryption key on
the fly for bi-directional web services security.

I'm not sure how I can accomplish this goal with the traditional
keystore mechanism.  Any suggestions & comments are of course welcome.
