SSF and digital signatures

Hi Guys!

I need to exchange XML document with third-party. Unfortunately, we need to sign this XML using XADES digital signature and smartcard reader. The default SAP Crypto does not suport devices like smartcard readers and we should use different company product.

Did you ever create such solution? Could you please help me in this area? Currently I cannot even find a software that could replace SAP CryptoLib.

Best regards

Ana
