If you want to change the information contained in the certificate (eg add/remove/change email address), send the request by e-mail to ra@cesnet.cz. Describe clearly the changes requested in your application. Specify the complete certificate subject in which you want to make changes. The application must be signed with your existing valid certificate.

The registration authority will verify the validity of the requested changes - you will be asked to confirm the validity of the functionality of the newly added email addresses, similar to the initial registration.

Upon successful verification, the registration authority will make changes to your certificate record and send you the activation data for Certificate Generator.
