Hello

Below is a copy of a notice we had on our account with Authorize.net please be advised:

Important: Security Certificate Upgrades on May 26th

Authorize.Net is upgrading our infrastructure to enhance system performance and security. On May 26, 2015, we are upgrading to new security certificates, which are signed using Security Hash Algorithm 2 (SHA-2) and 2048-bit signatures. Most modern operating systems and web servers support certificates that use SHA-2, however, there is a concern that older software—especially software based on outdated versions of Java—may not.

Please contact your web developer or solution provider as soon as possible to find out if your website or payment solution will support the new security certificates.

If any updates are necessary, please refer your web developer to this blog post in our Developer Community, which has all of the certificate information they will need for this update. Our sandbox environment has already been updated so that your developer can validate that your solution will continue to work using SHA-2 signed certificates, prior to May 26th.

After the update is complete on May 26th, any website or payment solution that cannot validate SHA-2 signed certificates will fail to connect to Authorize.Net's servers.

Btw we do not have a problem that we know of yet. But we like to be proactive about our security matter! We are going to check with our domain host next.

Thanks
