Digital Signature Certificate algorithm

Former Member — Wed, 30 Sep 2009 04:00:50 GMT

Hi Friends

Please clarify below points as we are planning to use SHA 256 algorithm with digital certificate while signing using SECULIB libraray.

1) Does SAP support SHA 256 algorithm , if yes doesnt any additional library files are required.

2) Does SAP support SHA 256 algorithm differently from ECC6

Thanks

Lavanya
