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

Are you Magento store owner using any of the below versions and using Authorize.Net Direct Post payment method with MD5 based hash?

  • Magento Commerce 1.X.X
  • Magento Open Source 1.X.X
  • Magento Commerce 2.X.X
  • Magento Open Source 2.X.X
  • Magento Commerce (Cloud) 2.X.X

If yes, continue reading this important post!

However, if you installed Magento SUPEE 11155 patch, you don’t need to worry as this solution is already resolved in the security patch!

Uptill now, Magento used the MD5 based hash to implement the Authorize.Net Direct Post payment method. But not anymore after Authorize.net announced MD5 Hash End of Life & Signature Key Replacement!

After this announcement, the store owners will not be able to process secure payments using the Authorize.net Direct Post.

Authorize.Net is phasing out the MD5 based hash use for transaction response verification in favor of the SHA-512 based hash utilizing a Signature Key. It will stop supporting the MD5 based hash key use from June 28, 2019.

Not to worry, as Magento provides the patch that merchants need to apply and replace the existing MD5 hash with a Signature Key (SHA-512) in the Magento Admin configuration settings.

 

Follow the below steps to continue using the Authorize.Net Direct Post in the Magento stores!

Steps to Update Authorize.Net Direct Post from MD5 to SHA – 512 in Magento:

  1. Apply the patch
    Download the zip file for your Magento Version for the patch installation. You can also download these Pre Patched files from GitHub. Unzip the downloaded files and add them to your root Magento folder.

    Applied Patch and successfully add a signature key, but an order is still using MD-5 Key and in Magento admin still say update your authorization module. Any reason behind this?

    Why do your patched files differ from the patch itself?

      We have provided Pre-patched files which are easy to install which you can do using FTP as well which is helpful. The Patch files provided by Magento needs to be added using SSH.

    Meetanshi, MD5 will affect the stores that are built with a Magento versions below 2.3. Hence,

    Magento Commerce 1.X.X
    Magento Open Source 1.X.X
    Magento Commerce 2.X.X
    Magento Open Source 2.X.X
    Magento Commerce (Cloud) 2.X.X

    is kind of miss-leading.

    Magento versions that will be affected are

    Magento Open Source versions below 2.3.
    Magento Commerce versions below 2.3
    Magento Commerce (Cloud) versions below 2.3

    I am getting php error message after installing and trying to place order. I am running on 5.3 php, could that be an issue with this patch?

    The PHP-FPM error log is showing:

          You might be using the wrong version of PHP while running the compilation command. The return type declaration it is failing on requires PHP7+.

    So we have to have API Login ID, Transaction Key and Signature key in admin panel settings in Magento only ? We have to leave Merchant MD5 value blank?

      Hi Anil,
      You need to get a new Signature Key and add it to your Magento Admin configuration.

      To get the Signature key:

      1. Log into the Merchant Interface at https://account.authorize.net.
      2. Click Account from the main toolbar.
      3. Click Settings in the main left-side menu.
      4. Click API Credentials & Keys.
      5. Select New Signature Key. Review the options available.
      6. Click Submit to continue.
      7. Request and enter PIN for verification.
      8. Your new Signature Key is displayed. Copy this key to add to your Magento Admin configuration.

      To Update Magento Admin Configuration:

      1. Log into the Magento Admin.
      2. On the Admin sidebar, click Stores. Then under Settings, click Configuration.
      3. In the panel, click Sales then Payment Methods.
      4. Expand the Authorize.net Direct Post section.
      5. In the Signature Key enter the SHA-512 Signature Key.
      6. Click Save Config.

      You have to keep the MD5 value blank as it has no more concern after the patch installation.

    Hi

    I have successfully downloaded and applied the patch. But when i execute php magento setup:di:compile following error occurs

    [RuntimeException]
    Class Magento\Sales\Api\PaymentFailuresInterface does not exist in [Magento\Authorizenet\Model\Directpost\Interceptor]

    I have confirmed it multiple times by reverting back the Authorize net module in vendor. Any fixes?

    Hi,
    I have downloaded the file : CE-2.0.0-CE-2.3.0.zip
    I did the extraction.
    I lost the site and the admin panel.
    I opened Putty to re-index with SSH CLI-commands
    The first mistake was on line 1108 of directpost.php : private function getOrderFromResponse(): \Magento\Sales\Model\Order
    Putty suggested to use ; or {
    I put ; instead of :
    When I re-indexed the mistake now is : namespace Magento\Authorizenet\Model;
    It say’s that it must be the first instance. But it is !!!

    I put the old directpost.php so I could see the website and the admin panel. Now I freeze when I try to checkout, witch is normal.

    Can you help ?

    Regards,

    Robert

    I am using Magento 2.1.7

      Hi Robert,
      You need to compile current Magento store using bin/magento setup:di:compile command.

    Hi – what about if you use the M1 authorize.net method? Is that affected at all? It is ambiguous in the Magento instructions as it is mentioned as AIM – https://support.magento.com/hc/en-us/articles/360024368392 – under Issue

    Magento implements the Authorize.Net Direct Post payment method, using Authorize.Net’s AIM (Advanced Integration Method) and DPM (Direct Post method) APIs, which use MD5 based hash.

    Authorize.net will stop supporting MD5 based hash usage on March 14, 2019. Starting from this date, Magento Open Source, Magento Commerce and Magento Cloud merchants will not be able to process payments using Authorize.Net Direct Post payment method. To be able to continue successfully process payments using these methods, merchants need to apply the patch provided by Magento and replace the existing MD5 hash with a Signature Key in the Magento Admin configuration settings.
