Authorize.net md5 hash phase-out

[crockettdunn]

If I am using the Authorize.net payment gateway as it shipped with AC Gold, are my transactions encrypted with the MD5 hash value configured in the Authorize.net merchant admin?

I received an email from authorize.net that my client has an MD5 hash value configured, and it is being phased out.

In practice, I don't see anywhere in the AC Admin where this setting is configured.

My concern is that it was years-ago configured and forgotten, and I'll end up with a broken checkout when Authorize.net disables it.

Thanks for your help.

Hello,

We have confirmed this will NOT affect your installation. We never required the setting of the MD5 hash during the setup of Authorize.net.

that's what I thought. Thanks for confirming!
