If you no longer want to use one of the CAs in your signature
digital certificate list, you must delete the CA root digital certificate.
Note: Before deleting a CA root digital certificate, create
a backup copy in case you later want to recreate the CA root.
To delete a CA root digital certificate from a database, use
the following procedure:
- Unless you are already using Key Manager, start the tool
by typing:
- From the main screen, select Open from the Key Database File list.
- Highlight the key database file from which you want to
delete a CA root digital certificate and click Open.
- Enter the password and click OK.
After your password is accepted, you are returned to the Key Management screen. The title bar shows the name
of the key database file you selected, indicating that the file is
now open and ready to be edited.
- Select Signer Certificates from
the Personal/Signer Certificates list.
- Highlight the certificate you want to delete and click Delete. The Confirm screen is
displayed.
- Click Yes. You are returned to the IBM® Key Management screen.
The label of the CA root digital certificate no longer appears in
the Signer Certificates field. You can either perform other
tasks or exit the tool.
