On this page, you can download the root certificates, issuing CA certificates, Certificate Revocation Lists (CRL) and service certificates. Also, there is a separate tab for certificates for testing.

Certificates can be downloaded in either DER or PEM format. All certificate validity times are in UTC.


If the CA issues a CRL, it is available to download. Not all CAs have a CRL available. CRLs are cumulative and include information about all the certificates in suspended (on Hold) or revoked status. If the suspension of a certificate is terminated, the certificate is removed from CRL. Certificates that are declared as not valid remain in the CRL at least until they expire.
