Backup Windows 8
- Private key (also data for the creation of an electronic signature),
- Public key (also data for the authentication of an electronic signature), usually a part of the certificate,
- The certificate itself.
In order for your certificate to be used correctly, you have to have a private key associated with the certificate, which is used to create the electronic signature. If you use a hardware solution such as smart card or USB token, the private key is located on such a medium and it is not necessary to do the backup. If you only use a PC, we recommend creating a backup.

After the certificate is issued, you already have all its parts available (private key, certificate with public key). If you only use a PC, we recommend that you back up the certificate with the appropriate keys. This backup is used for disaster recovery needs or for transfer to another device.
A backup (export) of a certificate can be created only if the certificate was designated as exportable.
