Pathfinder PKI Daemon 0.1.0

Pathfinder PKI Daemon is designed to provide a mechanism for any program to perform RFC3280-compliant path validation of X509 certificates, even when some of the intermediate certificates are not present on the local machine. The project will automatically download any such certificates (and their CRLs) from the Internet as needed using the AIA and CRL distribution point extensions of the certificates it is processing.

By default, the Pathfinder daemon listens on the D-Bus system bus for incoming requests. In this way, any project can easily gain the ability to reliably validate the trustworthiness of X509 certificates. For the convenience of those using OpenSSL or NSS (Netscape Security Services), two libraries containing a callback suitable for use with an SSL connection are provided with the main Pathfinder distribution.

If you are looking for a demonstration of Pathfinder, you may be interested in Pathviewer, which provides a graphical view of path validation via a GTK+ interface.
