How to Download & Install Sectigo Intermediate Certificates - RSA

Intermediate certificates - RSA

All subscriber certificates are issued by an Intermediate Certificate. These Intermediate Certificates are issued by our Trusted Root Certificate. We refer to the Intermediate Certificate as the Issuer CA certificate. The Issuer may vary depending upon the type of certificate and we send Intermediate Certificates with the subscriber certificate.

We recommend that you install the Intermediate Certificate on a Server. This will help build the trust chain between Root and End Entity Certificate, hence we call them "chain certificates".

You can also download the required Intermediate Certificate from the table below.

Note: Few legacy systems, that no longer receive any updates from their vendor, may not trust our SHA-2 Certificates. To enable them to trust our SHA-2 Certificates, we recommend our customers to include the Cross Signed Certificate into the Server Certificate chain. This will enable those legacy systems to trust our SHA-2 Certificates.

* SHA-1-based signatures for trusted root certificates are not a problem because TLS clients trust them by their identity, rather than by the signature of their hash.
