How To: Set the Public Key Size for PFX Certificate Enrollment

Version Affected: All
 
 

Overview

When a user enrolls for a PFX certificate, the certificate's public key defaults to 1024 bits. This covers how to change that default to a 2048-bit public key instead, for organizations that require the stronger key size.

1. Decrypt the realm's web.config.
2. Find the InstallCertType app setting:
   

   <add key="InstallCertType" value="1024" />

3. Change its value to 2048:
   

   <add key="InstallCertType" value="2048" />

4. Save and re-encrypt the web.config.

New PFX certificate enrollments for this realm now use a 2048-bit public key.
