To provide best-in-class consumer protection, Notarize will deprecate support for TLS 1.1 on February 1st, 2020. Once the change is made, the Notarize platform will only allow TLS 1.2 for all browser and API connections.
All major modern browsers support TLS 1.2 natively, so the change will be transparent for most of our customers. However, those who use legacy browsers like IE 10 or IE 11 on Windows 7 will need to upgrade to continue using Notarize.
Our API partners and integrators should confirm their stack supports TLS 1.2. A number of older frameworks – such as Java 6 or .NET 3.5 – do not have built-in support for TLS 1.2, so you will need to upgrade your application to avoid interruptions. To test your application against various versions of TLS, we recommend using this SSL project and its hosted testing tools.
Why this change, and why now? Embracing TLS 1.2 has been an industry trend for a few years, and has accelerated after recent patches to critical vulnerabilities found in TLS 1.1. Ultimately, TLS 1.2 is a newer and much safer cryptographic protocol.
