Using this we validate that
- The certificate is valid
- The private key is valid
- The passphrase decrypts the private key
- The private key matches the certificate

By validating this up front the user doesn't need to validate this
using trail and error.

This allows an admin to provide a client certificate and private key
to perform TLS client authentication on the external authorization
service.

Optionally a passphrase for the key can be provided.
