Email Certificates via TCS

Requirements for a Personal Email Certificate

  • You must be a "designated person" (you will then see the link "E-Mail Certificate" in your TUGRAZonline business card).
  • You need an email address assigned by TUGRAZonline (@tugraz.at or @student.tugraz.at) - only for these addresses certificates can be obtained this way!
  • You need a computer with internet access and the possibility to save files.

For non-personal addresses (e.g. office.INSTITUT@tugraz.at) please use the following form.

Step 1: Apply for Email Certificate

For a certificate for your personal email address open with your preferred browser the page

https://cert-manager.com/customer/ACOnet/idp/clientgeant

There, after SSO login, the easiest way is to select the combination "GÉANT Personal Certificate", 3 years/1095 days, „Key generation“ and "RSA 4096".

Choose a secure password to protect your certificate.

Step 2: Save Email Certificate

You will now be offered a file in p12 format for download. Save this file either on your hard disk or (if you want to install the certificate on several computers) e.g. in the TU Graz Cloud.
By double-clicking on this file the certificate will be integrated into the certificate manager of the operating system (macOS: Keychain or Windows: Certificate Manager). For this purpose it is necessary to enter the password selected above and possibly also the password of your account on the computer.

If you want to install the certificate on a new computer or in another program, but the certificate file is no longer available, you must export the certificate from the old computer or the other program.

Step 3: Install Email Certificate

For email programs that use the certificate manager of the operating system, only the correct certificate has to be selected in the e-mail program; for other programs, the p12 file has to be imported in each client that you want to use.

There are also apps for Android that can handle S/MIME, e.g. R2Mail2 from Austria.
