Authorize.Net Drops MD5

Authorize.netAuthorize.Net just announced they are phasing out MD5 based transHash support 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.  

eCommerce geek details, but still important for software developers and security experts.

Merchants utilizing this feature will need to work with their 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.
