How to reissue Certum S/MIME ?

Select the Certum S/MIME certificate suitable for your needs in the store and add it to your shopping cart.
After selecting the service(s), check the contents of the shopping cart and then confirm the order by clicking the Place the order button.
If you have not logged into your store account before, choose one of the options:

Fill in the address information and make sure the data is entered correctly. Data for the certification application will be provided only at the stage of activation of the certificate.
Choose the appropriate payment method:

  • Quick transfer
  • Standard transfer

Once all steps have been completed, the purchase will be finalized and the certificate will be available for activation. Check how to activate a certificate.


Mechanism: Certificate Reissue.

If a certificate Reissue is to be performed, only one, most recent certificate may remain valid. A certificate for which a Reissue has been performed will be automatically revoked 2 weeks after using the certificate Reissue mechanism. This is the time to swap certificates on the server.

Because of this, we encourage all users using the Reissue mechanism to install the reissued certificate immediately, in order to maintain certificate continuity on the website.
