Enforcing TLS Version 1.2? ›

Procedure. To enforce the use of TLS 1.2 on your site, ensure that all supporting software is using TLS 1.2: By default, WebSphere Application Server supports only TLS 1.0 for outbound communication. It is recommended that you use SSL_TLSv2 so that you can support TLS 1.0, 1.1, and 1.2 for outbound communication.

-Press the Windows key + R to start Run, type regedit, and press Enter or click OK. -If you can't find any of the keys or if their values are not correct, then TLS 1.2 is not enabled.

If you are running Windows 10 or 11, follow these steps below to do this thing: Step 1: Press Win + I to open Run, type inetcpl. cpl, and click OK to open the Internet Properties window. Step 2: Under the Advanced tab, scroll down to find Use TLS 1.2.

Click the Tools icon (gear symbol) in the upper right hand corner of the browser and click Internet Options. In the Internet Options window, select the Advanced tab. In the Advanced tab, under Settings, scroll down to the Security section. In the Security section, check Use TLS 1.1 and Use TLS 1.2.

Enter the URL you wish to check in the browser. Right-click the page or select the Page drop-down menu, and select Properties. In the new window, look for the Connection section. This will describe the version of TLS or SSL used.

Based on TLS 1.1, TLS 1.2 was released by the IETF in 2008 with the RFC-5246. To date, it's the most commonly used TLS protocol version. It's supported by 99.9% of the websites analyzed by SSL Labs (as of January 2023). Yup.

Transport Layer Security (TLS) 1.2 is the successor to Secure Sockets Layer (SSL) used by endpoint devices and applications to authenticate and encrypt data securely when transferred over a network. TLS protocol is a widely accepted standard used by devices such as computers, phones, IoTs, meters, and sensors.

How to check if TLS 1.2 is enabled? If the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\DisabledByDefault is present, the value should be 0.

Under TLS Versions, you will see the TLS protocol version(s) currently selected. To update the protocol, simply click edit. Next, choose your desired protocol based on your requirements and hit Save Changes. Please note that you can not disable TLS v1.

Certificate issues: Revoked, inactive, or expired certificates can cause TLS errors. A handshake failure may also occur when the hostname doesn't match the common name (CN) in the certificate.

Click Start or press the Windows key. In the Start menu, either in the Run box or the Search box, type regedit and press Enter. The Registry Editor window should open and look similar to the example shown below. Check the subkeys for each SSL/TLS version for both server and client.

Ensure that TLS 1.2 is enabled as a protocol for SChannel at the operating system level. For the most part, protocol usage is controlled at three levels, the operating system level, the framework or platform level, and the application level. TLS 1.2 is enabled by default at the operating system level.
