/*
* This is an implementation of SSL certificate authentication, which is
* overloaded with pgp style signatures, and web-of-trust authentication.
*
* only the owner ssl cert is store, the rest is jeus callback verification
*
* To use as an SSL authentication system, you must use a common CA certificate.
* and compilation should be done with PQI_USE_XPGP off, and PQI_USE_SSLONLY on
* * The pqissl stuff doesn't need to differentiate between SSL, SSL + PGP,
* as its X509 certs.
* * The rsserver stuff has to distinguish between all three types ;(
