Hello,

I am currently testing an AS4 communication solution (BDEW profiles) for one of our partners in the energy market.

In order to participate in AS4-based market communication in accordance with SM-PKI specifications, a Certificate Signing Request (CSR) must be created for a test certificate from Deutsche Telekom Security GmbH.

Could someone please let me know if they can provide specific tools, scripts, or instructions to help with the creation of such a CSR?

Thank you in advance for your assistance.
