Important information for developers

Attention developers: as of today, our certificates will be converted to "Generation 09".

From now on, e.g. the Handy-Signatur or ID Austria certificates will be issued by https://www.a-trust.at/certs/a-sign-premium-mobile-09.cer.

You can find a list of all certificates at https://www.a-trust.at/en/root_certificates/. Please take this into account, e.g. for MOA installations.

Information for Adobe users:With the new generation of certificates, there may be difficulties displaying the validity of your signature in Adobe Reader in the coming days. Until the latest certificates have been synchronized by Adobe, you can check the validity of your signatures at any time in the RTR signature verification tool or the A-Trust Website.
