    During installation, please always note the security advice and compare the data displayed with the data given here to ensure that you are installing the original A-Trust certificates!

     

     

    As the A-Trust root certificates are signed by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR), you can also download this certificate from our homepage for your convenience.

    The certificates listed here are available for download in the .crt format (DER encoded), as is required for example by Internet Explorer.

    In order for browsers such as Netscape Navigator, Mozilla or other (server) applications to be able to resolve the certificate chain, additional intermediate certificates must be installed.
