Authorize Net Important TLS 1.0 Disablement Notice

Authorize.Net Merchants

If you are an After Dark Grafx customer and are utilizing the Authorize Net Payment Gateway, you do not need to do anything in most cases. If you have questions, please contact our support department.

As you may or may not be aware, new PCI DSS requirements state that all payment systems must disable early TLS by 2018.

Transport Layer Security (TLS), is a technology used to encrypt sensitive information sent via the Internet. TLS is the replacement for Secure Sockets Layer (SSL).
In preparation for this requirement, Authorize.Net plans to disable TLS 1.0 and TLS 1.1 on the following dates:

Production: September 18, 2017

Authorize Net has disabled the sandbox in advance of production to allow you and your developers time to test your website or payment solution and ensure you are no longer using TLS 1.0 or 1.1 prior to September 18th.

Please contact your web developer or payment solution provider, as well as your web hosting company, to confirm that they can support TLS 1.2 for your API connections.
In addition, we plan to retire the 3DES cipher (a data encryption standard) in production on September 18th as well. Please refer your developer or solution provider to our API Best Practices for cipher recommendations, details about TLS 1.2 platform support, and other integration suggestions.

Note: If you are not using the current version of your web browser, please take a few moments to upgrade it now. Browsers released prior to 2014 may not support TLS 1.2. You can check your browser’s TLS support by visiting

If you have any questions about this email or the upcoming TLS disablement, please refer to our TLS FAQs within your Authorize Net Account.

Thank you,
