Thanks a lot Bhavesh for the response.
In our landscape, we are using Advantco not Seeburger. Does Advantco also support SHA2 algorithms?
As you suggested, SHA256 certificate based algorithm can continue to be used for SHA1 signing algorithm. Does it hold for Advantco AS2 as well, any insight?
If yes, I think we will not have any problem if SHA1 signing supports SHA256 certificate.
Thanks,
