Modify CA in Certificate Manager

This article includes updates for CM 8.10.

This article describes how to change certain parameters of a Certificate Authority (CA) in Smart ID Certificate Manager (CM). The name of the CA can be modified and the CA can be closed or reactivated.

Furthermore, CM includes functionality to renew CA certificates without breaking the certification chain of already issued end user certificates. Renewed CA certificates must replace the existing ones in the trust stores of all third party client software, server software and devices. The serial number and signature of the renewed CA certificate will differ from the certificate it replaces. A later expiry date and a different signing algorithm can optionally be chosen at time of renewal. After renewal, the old certificate will not remain in the database.

This task is done in Administrator's workbench (AWB).


The following prerequisites apply:

  • Two administration officers must sign the request.

  • Both officers must have the following roles:

    • Use AWB

    • CA and Key tasks

A connection to the CM host must have been established. See Connect to a Certificate Manager host.
