MD5 Hash

The MD5 Hash security feature allows you to authenticate transaction responses from the payment gateway. You can establish a unique MD5 Hash value that the payment gateway will use when encrypting responses for transactions submitted for your account.

For more information about the MD5 Hash feature, please review the SIM Implementation Guide or contact your Web developer.


To add or edit an MD5 hash value:

Step 1: Enter the desired hash value in the New Hash Value text field.

Step 2: Enter the value again in the Confirm Hash Value text field. This value must match the value entered in the New Hash Value text field exactly.

Step 3: Click Submit. A confirmation message indicates that your setting has been successfully applied.


Note: The MD5 Hash will be passed in transaction responses even if you do not set an MD5 Hash Value.
