End of support for CBC ciphers in TLS connections

DigiCert will end support for Cipher-Block-Chaining (CBC) ciphers in TLS connections to our services on October 8, 2022, at 22:00 MDT (October 9, 2022, at 04:00 UTC).

This change affects browser-dependent services and applications relying on CBC ciphers that interact with these DigiCert services:

  • CertCentral and CertCentral Services API
  • Certificate Issuing Services (CIS)
  • CertCentral Simple Certificate Enrollment Protocol (SCEP)

This change does not affect your DigiCert-brand certificates. Your certificates will continue to work as they always have.

Why is DigiCert ending support for the CBC ciphers?

To align with Payment card industry (PCI) compliance standards, DigiCert must end support for the following CBC:

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
  • TLS_RSA_WITH_AES_256_CBC_SHA

What do I need to do?

If you are using a modern browser, no action is required. Most browsers support strong ciphers, such as Galois/Counter Mode (GCM) ciphers, including Mozilla Firefox, Google Chrome, Safari, and Microsoft Edge. We do recommend updating your browser to its most current version.

If you have applications or API integrations affected by this change, enable stronger ciphers, such as GCM ciphers, in those applications and update API integrations before October 8, 2022.

If you do not update API integrations and applications, they will not be able to use HTTPS to communicate with CertCentral, the CertCentral Services API, CIS, and SCEP.
