Info: Is there a Limit on the number of SANs that can be assigned to a Certificate?

Applies To:

All supported versions of Venafi TPP

Summary:

Question: When adding SANs to the certificate, is there a limit to the number of SANs that can be added?

Answer: Not for Venafi, but maybe for the associated Certificate Authority.

More Information

Within the construct of the Venafi Trust Protection Platform, each SAN entry is a new row in the database. You can literally add as many as you want. However, when the CSR is submitted, the CA may reject after a certain length, and in fact, most CA's do have a limit in length.

Thus, if you're getting an error about the length of the SAN entry, check with your CA.
