Digital Signature Certificate algorithm

[Former Member]

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
