Key notes

Transport Layer Security (TLS 1.2), also known as Transport Layer Security, is an encryption protocol designed to keep users’ data safe when the data is transferred over a network. The TLS 1.2 protocol is similar to the SSL (Secure Sockets Layer).

Transport Layer Security (TLS 1.2) is mainly used by client-server applications to share data and information across a network without security breaches or information leaks.

It functions to provide confidentiality, authenticity, and integrity by employing certificates between the computer applications sharing information.

How can I check if TLS 1.2 is enabled?

How can I check if TLS 1.2 is enabled?

Transport Layer Security was introduced in 1999 as an Internet Engineering Task Force and has since evolved, with TLS 1.2 introduced in 2008.

Transport Layer Security has two levels of operation: the TLS handshake protocol and the TLS record, and the TLS operates in the application layer.

TLS 1.2 is more than just an upgrade; it is an essential step to ensuring safe data sharing. Older versions of the Transport Layer Security have become susceptible to attacks and security breaches easily avoidable with TLS 1.2.

Ensure that the TLS version is updated to TLS 1.2. and TLS 1.2. is enabled on your system to protect your data.

TSL 1.2 and 1.3 are enabled by default on Windows 11. You can also read this piece to learn more about how the protocol works.

The quickest way to check whether TLS 1.2 is enabled on your computer is to search for the presence of the registry key.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\EnabledAnd its corresponding value,1.

What is the command to check the TLS version in Windows?

What is the command to check the TLS version in Windows?

You can check the version of TLS 1.2 in Windows using the command:openssl s_client -connect www.google.com:443 -tls1_2. You’ll be able to tell whether the version is supported if you get the certificate chain and handshake. Otherwise, you will get the handshake error message.

How do you check which TSL protocol is being used?

There are different TLS protocols, with the latest being 1.3. You can view the currently used ones by noting which ones have checked boxes.

How do I enable TLS 1.2 on Windows?

1. Enable TLS 1.2 on Windows 11

2. Enable TLS 1.2 on Windows 10

1. Open Google Chrome.

  1. Press theAlt+Fkeys.

  2. Click onSettings.

  3. Go toAdvanced.

  4. Scroll down and selectSystem.

  5. Click onOpen your computer’s proxy settings.

  6. Press onInternet optionsand selectAdvanced.

8.Scroll down and click onsecurityand tick theuse TLS 1.2box.

  1. ClickOK.

  2. Close the browser window and relaunch the browser.

On Windows 10, TLS 1.2 can be easily enabled via Internet Options, directly from the Google Chrome browser. The settings will take effect as soon as you restart your PC.

3. Enable TLS 1.2 on Windows 7

4. Enable TLS 1.2 on Windows Server 2019

5. Enable TLS 1.2 on Windows Server 2016

6. Enable TLS 1.2 on Windows Server 2012 R2

How can I upgrade from TLS 1.0 to TLS 1.2

Older TSL versions are less secure than the latest ones. So you can also read more aboutdisabling the TSL 1.0 protocol. If your device runs the latest Windows version, version 1.3 will be present.

Sometimes, Windows 11 users can experienceTSL errors. Our guide provides a comprehensive solution.

As earlier emphasized, TSL 1.3 is automatically enabled on modern Preview builds of Windows. As far as internet security deployment protocols go, TSL 1.3 is the standard. Its secure protocols are made in such a way as to facilitate endpoint-to-endpoint data transfer. That is, it provides an additional security layer for client-server communications.

The new protocol addresses most of the failings of previous versions, making cryptographic algorithms obsolete. As a result, the handshake protocol (client authentication) is greatly encrypted and enhanced.

In addition, TSL 1.3 sees a marked improvement in privacy. The implication is that the network’s visibility of your user details and information is severely limited.

Having made it this far in this article, you’re sure to have found multiple solutions to enabling the TSL 1.2 protocol on your computer. If you’ve found this article interesting and valuable, please share your experience in the comments below.
