I am trying to upgrade sage pay version from 2.22 to 3.00 and I am using Form Intergration to submit the values to Sage. The codes written VB. In 2.2, it was using "SimpleXor encryption algorithm", but that doesn't allowed in version 3.00 and as a result, I am getting the below error message:
This transaction attempt has failed. We are unable to redirect you back to the web store from which you were purchasing. The details of the failure are given below.
Status: INVALID
Status Detail: 5068 : The encryption method is not supported by this protocol version.
I found, version 3.00 allowed only AES encryption. Is there any sample AES encryption code to fix this issue?
Thank you in advance.
