The Certificate Revocation List (CRL) is a periodically issued list of digital signature certificates that have been suspended or revoked prior to their expiration dates. It is digitally signed by Tata Consultancy Services - Certifying Authority (TCS-CA).

TCS-CA shall update and issue the CRL whenever Certificates are revoked or suspended as well as on the 1st working day of each month. The CRL issued will be published immediately and the same can be downloaded from the Download link.

The Controller of Certifying Authorities (CCA) certificate, Tata Consultancy Services - Certifying Authority (TCS-CA) certificate and the subscriber's digital certificate form the Certificate Chain.

In order for the subscriber's digital certificate to be validated (while encrypting or digitally signing S/MIME messages, or while making https connections with a TCS-CA certified web site), both the CCA and the TCS-CA certificates are mandatory.
