Certificates can be self-signed or created through a Certification Authority (CA). If you lose or delete a self-signed Digital ID, you will no longer be able to open files protected by it. If your Digital ID was created through a CA, you can retrieve the ID from them.
The program allows you to download multiple security certificates from the Windows Certificate store.
