Today Morning I got an Email from the authorize.net regarding MD5 Hash Removal/Disablement. Here what exactly they stated.
Authorize.Net is phasing out the MD5 based transHash element in favor of the SHA-256 based transHashSHA2. The setting in the Merchant Interface which controls the MD5 Hash option will be removed by the end of January 2019, and the transHash element will stop returning values at a later date to be determined. Merchants utilizing this feature will need to work with their web developer or solutions provider to verify if they are still utilizing MD5 based hash and if still needed to move to SHA-256 hash via Signature Key.
Currently I am using CiviCRM 4.7.29 version. Integrated with Drupal 7.
In payment Processors settings. I am using Authorize.Net as Payment Processor Type. And Using MD5 hashing also.
Now my question is. Does the latest version 5.9 supports this feature? Or Please let me know is their any other alternate solution.
