Certificates for Digital Signatures

We accept personal certificates issued by any widely respected certification authority (CA). This includes certificates by CAs organized in International Grid Trust Federation, its European branch EUGridPMA and its member organizations, e.g. the CESNET certification authority. The Czech "Qualified certificate" (Kvalifikovaný certifikát) provided by PostSignum or I.CA, which is used in electronic contact with Czech authorities, is accepted as well. In general, we accept certificates issued by any trusted CA that ensures unambiguous identification of the user.

Certificate generation process for academic purposes, utilizing the CESNET certification authority, is well described here:


The certificate file can be installed into your email client. Web-based email interfaces cannot be used for secure communication, external application, such as Thunderbird or Outlook must be used. This way, your new credentials will be visible only in applications that have access to your certificate.

If you are not able to obtain the certificate from any of the respected certification authorities, follow the Alternative Way below.

FAQ about certificates can be found here: Certificates FAQ.

Alternative Way to Personal Certificate


Choose this alternative only if you cannot obtain your certificate in a standard way. Note that in this case you must attach a scan of your photo ID (personal ID, passport, or driver's license) when applying for login credentials.

An alternative to personal certificate is an S/MIME certificate allowing secure email communication, e.g. providing sensitive information such as ID scan or user login/password.

The following example is for Actalis free S/MIME certificate, but you can choose your preferred CA.

  1. Go to the Actalis Free Email Certificate request form.
  2. Follow the instructions: fill out the form, accept the terms and conditions, and submit the request.
  3. You will receive an email with the certificate.
  4. Import the certificate to one of the supported email clients.
  5. Attach a scan of photo ID (personal ID, passport, or driver license) to your email request for IT4I account.


Web-based email interfaces cannot be used for secure communication; external application, such as Thunderbird or Outlook must be used. This way, your new credentials will be visible only in applications that have access to your certificate.
