How can I verify the SSL certificate?

The openssl verify utility can be used to verify and validate certificates against known CAs.

In order to verify CDRouter’s default ACS server certificate, which is signed by Comodo, using the openssl verify utility, you must also specify the intermediate and root CAs ( ca.pem and rootca.pem, respectively) using the -CAfile option:

# openssl verify -verbose -CAfile <(cat OK

Note that all of CDRouter’s certificates are located in the /usr/cdrouter/tests.
