Attention!
Risk of data loss!

With this certificate, you can digitally sign emails and/or send and receive encrypted messages.

Please note that encrypted emails are no longer readable without the corresponding certificate!
Even if the certificate has already expired, it will still be needed!

You have no control over others sending you encrypted emails. Store the certificate (especially the private key) and the associated password in a safe place.

The ITS cannot help you if the private key and/or password gets lost. Encrypted emails are then irretrievably lost and can no longer be read or restored from a backup.

This is how you can download your certificate:

1

Open the URL https://cm.harica.gr
Click on Academic Login.

Under Find Your Institution, search for Bayreuth and click on University of Bayreuth.

You will be redirected to the login page of the Uni Bayreuth. Please enter your Uni Bayreuth username and password.
After that, click Login.

Click Informationen übertragen on the now appearing page.

Attention!
Under E-Mail, you can see the address that will be used for the certificate. This is your Standard e-mail address which can be set in the ITS Portal (https://portal.its.uni-bayreuth.de). It is very important that you use this exact address to send your e-mails later, otherwise the recipient will see an error message.

Attention!
Keep the password in a safe place. There is no way to recover it if it gets lost!
