If you no longer require a private certificate, you can revoke the private certificate in the Certificate Management Service console before the private certificate expires.
Private certificates that are revoked or deleted are no longer trusted by the internal environments of enterprises and cannot be restored or re-enabled. Proceed with caution.
Log on to the Certificate Management Service console.
In the left-side navigation pane, choose . On the PCA Certificate Management page, select the region where your PCA resides.
On the Private CAs tab, find the private intermediate certificate authority (CA) from which the required private certificate is issued and click Certificates in the Actions column.
On the Certificates page, find the private certificate that you want to revoke and click Revoke in the Actions column.
In the Confirmation message, click Revoke.
The private certificate is immediately revoked. After the value in the Status column of the private certificate changes to Revoke, you can delete the private certificate from the list of private certificates.
