## Using the Trust Policy Module with NSS

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.
