Airship TLS 1.0 and 1.1 Sunset FAQ

On July 20th, 2021 at 10:00am PDT; Airship will be removing support for TLS 1.0 and 1.1 cipher support for our APIs.  

We are removing these older security methods to ensure best of class security and data protection measures for our customers. We will be requiring that all API requests use at least TLS version 1.2, which was introduced in 2008.

What is TLS and why is Airship removing support for older versions?

TLS is a handshake layer that is performed to establish a secure network. TLS is used for all website and API connections to Airship. 

TLS 1.0 & 1.1 (launched in 1999 and 2006 respectively) have been replaced by the newer versions of TLS 1.2 & 1.3.  While Airship has continued to support TLS 1.0 & 1.1 for some time, Industry support stopped in 2008 when TLS 1.2 launched. In 2017 all PCI compliance required TLS 1.2 or greater and in March of 2020, modern browsers stopped supporting TLS 1.0 & 1.1.  Removing these legacy ciphers allows us to complete a required upgrade in security for our overall network.

Which TLS 1.2 ciphers will be supported?

The following TLS 1.2 (or greater) ciphers are supported by Airship:


Please note, depending on the programming language/library you are using to make API requests, the naming conventions of the suite may very slightly. Consult the language/library's documentation for precise naming conventions.

Am I impacted?

Airship’s Customers on our US Customer Site with legacy integrations with Airship dating 5 years or older may need to update their Airship server or security libraries. 

Why is this happening?

We are required to sunset support for TLS 1.0 and 1.1 to comply with GDPR and CCPA regulations.
