libpathfinder-dev 1.1.3-0.4 (i386 binary) in ubuntu precise

 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.
