By providing a cloud computing environment that supports the most recent security technologies, Amazon Web Services ( AWS ) aims to continuously enhance customer experience. We have now begun enabling TLS type 1.3 internationally across all of our AWS support API endpoints, and we will finish it by December 31, 2023, in an effort to enhance the overall efficiency of your connections. By using TLS 1.3, you may benefit from some of the most cutting-edge and safe crypto cipher suites currently on the market and cut down on connection time by eliminating one system round trip for each connection request.

 <p>If you are using current software tools (2014 or later) including our <a href="https://aws.amazon.com/developer/tools/" target="_blank" rel="noopener">AWS SDKs</a> or <a href="https://aws.amazon.com/cli/" target="_blank" rel="noopener">AWS Command Line Interface (AWS CLI)</a>, you will automatically receive the benefits of TLS 1.3 with no action required on your part. This is because AWS services will negotiate the highest TLS protocol version that your client software supports. If you want to continue using TLS 1.2, you will still have full control through your client configurations. AWS will retain support for TLS 1.2, in addition to TLS 1.3, into the foreseeable future. Meanwhile, here’s the latest information on the on-going deprecation of <a href="https://aws.amazon.com/blogs/security/tls-1-2-required-for-aws-endpoints/" rel="noopener" target="_blank">TLS 1.0/1.1</a>.</p> <p>If you have any questions, start a new thread on <a href="https://repost.aws/" target="_blank" rel="noopener">AWS re:Post</a>, or contact <a href="https://aws.amazon.com/support" target="_blank" rel="noopener">AWS Support</a> or your technical account manager.
