The trust policy module is a drop in replacement for the
libnssckbi.so
module and thus works out of
the box with NSS. The trust policy module provides NSS style
PKCS#11 trust objects for NSS to retrieve.
The module may be used to replace the
libnssckbi.so
file via an distribution
specific alternatives mechanism or otherwise.
Alternatively NSS applications like Firefox or Thunderbird
may be configured to use the trust policy module by adding
the p11-kit-trust.so
PKCS#11 module via their
GUI or command line configuration.
