Pathfinder is designed to provide a mechanism for any program to perform rfc3280-compliant path validation of x.509 certificates, even when some of the intermediate certificates are not present on the local machine. it will automatically download any such certificates (and their crls) from the internet as needed using the aia and crl distribution point extensions of the certificate it is processing.

this package contains the development files to allow programmers to write applications using either openssl or libnss that use pathfinder for their certificate validation.
