Warning

Previously, the bundles were provided with a .bundle extension. They are still available for download but are deprecated and we do not publish the corresponding filename checksum. Please migrate to the new .crt bundles as the .bundle names will be removed by end of September 2024.


  1. This bundle contains only the public versions of the cross-signed PKI certificates. Recommendeded for all systems where signatures must be verified by external partners. 

  2. This bundle contains only the internal versions of the cross-signed PKI certificates. Useful for air-gapped internal systems where signatures must be verified within Siemens only. 

  3. This bundle contains all non-Siemens intermediate certificates that we use. Must be installed along with one of the Siemens PKI bundles.
