Authorize Net has finally announced their MD5 Hash End of Life phase two, to stop populating the MD5 Hash value from their Production. The date will take on March 28, 2019.

What does this mean to VPCart merchants?
This means after March 28, 2019, the store owners that are still using old Authorize Net DPM or SIM payment gateway will not be able to take payments as both old gateways are still using MD5 Hash.

Who doesn't have to worry about this change?
For store owners that already using very latest VPCart Authorize Net AcceptJS or VPCart Authorize Net Accept Hosted gateway, then you are 100% safe.

What should I do if I am still using DPM or SIM?
Please don't get nervous, as VPCart has released the newer versions of Authorize Net payment gateway modules to replace the old ones.

Authorize Net DPM has been replaced with Accept.js method and Authorize SIM has been replaced with Accept Hosted method.
