Jared,

I'm not sure what exactly you mean by "signing like normal" as the signing
done by iText actually is quite normal.

If what you actually want is more complete control over the actual signature
container generation, i.e. at some point have a stream of bytes to sign,
create a signature container using your own or third party libraries, and
then inject that externally created signature container, the code here:

http://old.nabble.com/Re%3A-signing-pdf-with-external-signature-p22053082.html

might help you along.

Regards,   Michael.
