====== Installing a Custom CA Cert/SSL Decyption ======

Given a CA certificate file foo.crt, follow these steps to install it on Ubuntu:

Create a directory for extra CA certificates in /usr/share/ca-certificates:
<file>
sudo mkdir /usr/share/ca-certificates/extra
</file>
Copy the CA .crt file to this directory:

<file>sudo cp foo.crt /usr/share/ca-certificates/extra/foo.crt</file>
Let Ubuntu add the .crt file's path relative to /usr/share/ca-certificates to /etc/ca-certificates.conf:
<file>
sudo dpkg-reconfigure ca-certificates
</file>
In case of a .pem file on Ubuntu, it must first be converted to a .crt file:
<file>
openssl x509 -in foo.pem -inform PEM -out foo.crt
</file>
