9.19.1. Installation of p11-kit

Prepare the distribution specific anchor hook:

sed '20,$ d' -i trust/trust-extract-compat

cat >> trust/trust-extract-compat << "EOF"
# Copy existing anchor modifications to /etc/ssl/local
/usr/libexec/make-ca/copy-trust-modifications

# Update trust stores
/usr/sbin/make-ca -r
EOF

Prepare p11-kit by running the following commands:

meson setup p11-build     \
      --prefix=/usr       \
      --buildtype=release \
      -D trust_paths=/etc/pki/anchors

Compile the package:

ninja -C p11-build

To test the results, issue:

ninja -C p11-build test

Install the package:

ninja -C p11-build install
ln -sfv /usr/libexec/p11-kit/trust-extract-compat \
        /usr/bin/update-ca-certificates

9.19.2. Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D trust_paths=/etc/pki/anchors: this switch sets the location of trusted certificates used by libp11-kit.so.

-D hash_impl=freebl: Use this switch if you want to use the Freebl library from NSS for SHA1 and MD5 hashing.

9.19.3. Configuring p11-kit

The p11-kit trust module (/usr/lib/pkcs11/p11-kit-trust.so) can be used as a drop-in replacement for /usr/lib/libnssckbi.so to transparently make the system CAs available to NSS aware applications, rather than the static list provided by /usr/lib/libnssckbi.so. As the root user, execute the following commands:

ln -sfv ./pkcs11/p11-kit-trust.so /usr/lib/libnssckbi.so

Short Descriptions

p11-kit

is a command line tool that can be used to perform operations on PKCS#11 modules configured on the system

trust

is a command line tool to examine and modify the shared trust policy store

update-ca-certificates

is a command line tool to both extract local certificates from an updated anchor store, and regenerate all anchors and certificate stores on the system. This is done unconditionally on BLFS using the --force and --get flags to make-ca and should likely not be used for automated updates

libp11-kit.so

contains functions used to coordinate initialization and finalization of any PKCS#11 module

p11-kit-proxy.so

is the PKCS#11 proxy module
