XI and ELSTER (VAT) - Problem with encryption

Hello,

I'm realizing an VAT via ELSTER scenario with PI 7.0.

When I send the VAT from R/3 (ECC 6.0) to PI, I get the error "com.sap.aii.af.ra.ms.api.DeliveryException: Unsupported keysize or algorithm parameters" back from the adapter.

Can anyone help me?

regards christian
