Description
People are reporting that 2Checkout is no longer working. Upon further investigation, it appears they made a change in their API to switch from MD5 to SHA2/SHA3. See https://verifone.cloud/docs/2checkout/API-Integration/01Start-using-the-2Checkout-API/2Checkout-API-general-information/Migration_guide_SHA2_SHA3 for their "Migration guide".
We need to update the module to use SHA instead of MD5.
