Certification Authorities

Prior version 6.0 IP Fabric used the CA bundle shipped with node.js. This led to confusion as the system utilities were not aware of the new certificates. Starting with release 6.0 we have switched to global cert store as trusted by openssl.

Internally this is achieved with passing --use-openssl-ca to node.js.

Adding a custom certificate

You add certificate by placing .crt file to /usr/local/share/ca-certificates and running update-ca-certificates. We recommend creating a subdirectory in case you are planning to have multiple certificates added.

mkdir /usr/local/share/ca-certificates/my_custom_ca


Certificate has to be in PEM format with .crt extension, files with other extensions are omitted.

After placing the certificate there, you will need to run update-ca-certificates command to link the certificate to the Trusted Root Certificate Store. Running it should give you output similar to the following:

Updating certificates in /etc/ssl/certs...
1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...

Converting to .crt

.crt is nothing more than a PEM certificate with a custom extension. If you need to convert you certificate, you can use openssl command line tool to do so. It is typically pretty clever in guessing input format:

openssl x509 -in my_custom_ca.der -out /usr/local/share/ca-certificates/my_custom_ca.crt

Deleting a custom certificate

  1. Delete appropriate files / directories from /usr/local/share/ca-certificates/.
  2. Run update-ca-certificates.
