Certificates
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.
CERTIFICATE REVOCATION LIST (CRL)
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.
