Go to Internet Options> Advanced> Security section and check “Use SSL 3.0” and whichever other protocols/options you wish to enable then click OK.

Simply put, it’s up to you. Most browsers will allow the use of any SSL or TLS protocol. However, credit unions and banks should use TLS 1.1 or 1.2 to ensure a protected connection. The later versions of TLS will protect encrypted codes against attacks, and keep your confidential information safe.

There are two dependencies for TLS to work properly: Your browser needs to have TLS 1.0 and TLS 1.1 disabled. This should be handled by local desktop support if you are not the administrator of your machine. The website you are connecting to needs to have TLS 1.2 enabled.

In the Windows menu search box, type Internet options. Under Best match, click Internet Options. In the Internet Properties window, on the Advanced tab, scroll down to the Security section. Check the User TLS 1.2 checkbox.

Enable TLS 1.3

1. Open Chrome Developer Tools.
2. Click the Security tab.
3. Reload the page (Command-R in Mac OS, Ctrl-R in Windows).
4. Click on the site under Main origin.
5. Look on the right-hand tab under Connection to confirm that TLS 1.3 is listed as the protocol (see image below).

There are three tasks for enabling TLS 1.2 on clients:

1. Update Windows and WinHTTP.
2. Ensure that TLS 1.2 is enabled as a protocol for SChannel at the operating system level.
3. Update and configure the . NET Framework to support TLS 1.2.

To set TLS 1.2 by default, do the following:

1. Create a registry entry DefaultSecureProtocols on the following location:
2. Set the DWORD value to 800 for TLS 1.2.
3. For 64-bit OS, repeat step 1 and 2 on the following location:
4. Reboot the server and test.

Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used.

TLS 1.2 is enabled by default. Therefore, no change to these keys is needed to enable it. You can make changes under Protocols to disable TLS 1.0 and TLS 1.1 after you’ve followed the rest of the guidance in these articles and you’ve verified that the environment works when only TLS 1.2 enabled.

How to enable TLS 1.2 on Windows Server 2008/2016

1. In the Windows start menu, type regedit and open it.
2. We strongly recommend backing up your current registry before making any changes.
3. Go to the following path: Computer/HKEY_LOCAL_MACHINE/SYSTEM/

Right click on the Protocols folder and select New and then Key from the drop-down menu. Once you click on the key option, this will create a new folder “New Key #1”. You have to rename it with the name “TLS 1.2”. Right click on the TLS 1.2 key and select New and then Key from the drop-down menu.

3.1 – Enable TLS 1.1 and TLS 1.2 in Windows Schannel

1. Save the tls11-enable. reg file.
2. Double-click the tls11-enable. reg file.
3. Click Yes to update your Windows Registry with these changes.
4. Restart your computer for the change to take effect.

Instructions

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

1. Click on: Start -> Control Panel -> Internet Options 2. Click on the Advanced tab 3. Scroll to the bottom and check the TLS version described in steps 3 and 4: 4.

Enable TLS 1.2 manually

1. Open the Tools menu (select the cog near the top-right of Internet Explorer 10), then choose Internet options:
2. Select the Advanced tab.
3. Scroll down to the Security section at the bottom of the Settings list.
4. Select Use TLS 1.1 and Use TLS 1.2.
5. For extra security, deselect Use SSL 3.0.

To set the protocols to be used for secure connections,

1. Press Windows key + R to open a Run box, type control and press Enter.
2. Find Internet Properties and open the dialogue.
3. On the Advanced tab, scroll down to the Security section and select TLS 1.2 and TLS 1.3.

That in the registry TLS 1.2 should be enabled by default on Windows Server 2012 R2.

How do I set my TLS settings back to default?

1. Launch Internet Explorer.
2. Click the Tools button.
3. Click Internet Option.
4. Go to the Advanced tab.
5. Under Security section and check Use TLS 1.0, TLS 1.1, and TLS 1.2.

Configure TLS 1.2 for current PowerShell session

1. Run PowerShell as administrator.
2. To set TLS 1.2 for the current PowerShell session, type: Azure PowerShell Copy. $TLS12Protocol = [System.Net.SecurityProtocolType] ‘Ssl3 , Tls12’ [System.Net.ServicePointManager]::SecurityProtocol = $TLS12Protocol.

Click on: Start -> Control Panel -> Internet Options 2. Click on the Advanced tab 3. Scroll to the bottom and check the TLS version described in steps 3 and 4: 4. If Use SSL 2.0 is enabled, you must have TLS 1.2 enabled (checked) 5.
