Delete a CA Certificate

The CA certificates are stored in the file trusted.pem.

Where there are multiple certificates in a file, they are numbered in the order they are found. When you add and remove certificates in trusted.pem, the numbering changes. Ensure that you list the certificates immediately before you delete a certificate.

To delete a root certificate

1. List the certificates that are stored in the file trusted.pem, by using the following command:

   dxcertgen listca
   

2. Find the certificate that you want to delete, and note the number of this certificate.
3. Delete the certificate, using the following command:

   dxcertgen -r certnumber removeca
