It also obsoletes or changes other TLS features such as the OCSP stapling extensions ( RFC 6066, RFC 6961), and the session hash and extended master secret extension ( RFC 7627). TLS 1.3 is a new TLS version which supersedes and obsoletes previous versions of TLS including version 1.2 ( RFC 5246). We need to support TLS 1.3 to remain competitive and keep pace with the latest standard. Several early implementations from other vendors are available already. TLS 1.3 is a major overhaul of the TLS protocol and provides significant security and performance improvements over previous versions. It is also not a goal to support every feature of TLS 1.3 see the Description section for more details on what will be implemented. It is not a goal to support version 1.3 of the Datagram Transport Layer Security (DTLS) Protocol. In the results, click with your right mouse button and select ' Run as Administrator'.Implement version 1.3 of the Transport Layer Security (TLS) Protocol RFC 8446. For this, first follow the steps outlined in Microsoft's manual's below:Ĭlick the Windows Start button and type ' Notepad'. If you do however use TLS 1.0 and/or TLS1.1 additional steps are required:īefore actually disabling TLS 1.0 and 1.1, it's important that your Exchange server is actually ready for disabling TLS 1.0 and 1.1 and the exclusive use of TLS 1.2. In the top of the Registry Editor, enter the line ' HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\', or click the folder structure on the left until you reach this specific folder.ĭo you not see additional folders for TLS 1.0 and 1.1 but only TLS 1.2? Then you already don't use TLS 1.0 and 1.1 and are finished with this tutorial. This can easily be done by checking the Windows registry:Ĭlick on the Windows Start button, type ' regedit' and click on ' Registry Editor' in the search results. It's important to first check whether or not you actually support TLS 1.0 and/or TLS 1.1 as your server may already be up-to-date bent. Finally, reboot your VPS.ĭisabling TLS 1.0 and 1.1 for Exchange Server Save the changes and close the file ( ctrl + x > y > enter). In this tutorial we will show you how to check whether you are using TLS 1.2 or not and if so, how to disable TLS 1.0 or 1.1 on your mail server. Mail software is generally smart in its TLS usage and will automatically use the newest available version, meaning that if you support TLS 1.2 or newer, disabling 1.0 and 1.1 is optional (but recommended for security reasons). When using the VPS mail service, it is therefore important to ensure that you use TLS 1.2 or newer. Should you be unable to update your TLS version, we recommend disabling the VPS mail service and to instead mail from your VPS itself directly. However, for security reasons, we decided that as of the end of april 2022, we will no longer support these older TLS versions. This means that these versions will no longer be updated and their use is potentially unsafe.įor backwards compatibility, we have supported TLS 1.0 and TLS 1.1 on the VPS mail service until the end of 2021. Various TLS versions have been released over the years, of which TLS 1.0 and TLS 1.1 have already reached a so-called ' End of Life' status since June 2018. Nowadays, when people talk about SSL, they always mean TLS. For example, in order to secure the connection from your computer to a website or mail server. Transport Layer Security (TLS) is the successor to SSL and is used to secure communications on a computer network (e.g.
