How to Update Authorize.Net Direct Post from MD5 to SHA-512 in Magento

Authorize.Net is one of the oldest and most popular payment gateway providers for eCommerce. Established in 1996, the company is headquartered in American Fork, Utah. Since inception, the company has provided payment gateway services to over 400,000 merchants and later acquired by Visa in 2010. Magento’s comes with built-in integration of the Authorize.Net that uses MD5 based hash and recently Authorize.net will stop supporting MD5 based hash usage on June 28, 2019. So, the Magento merchants will not able to process payments using Authorize.Net Direct Post.

That’s the reason why we need to apply the patch provided by Official Magento and replace the existing MD5 hash with a Signature Key (SHA-512) in the Magento Admin configuration settings.
