FAQs

Is TLS 1.2 still supported? ›

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.

Create a key named "TLS 1.1" with two DWORDs for both TLS 1.0 & 1.1: "DisabledByDefault=1" & "Enabled=0". Similarly, create a key named "TLS 1.0" with two DWORDs for each protocol, "DisabledByDefault=1" & "Enabled=0".

You can check the TLS version for each server separately. Scroll down to the ″Configuration″ section to find all TLS versions marked ″Yes.″ In the "Protocols" section under "Configuration," you'll see a list of all TLS versions, and a simple "Yes" or "No" to indicate which of those versions are supported.

SQL Server 2019 has the same level of support as SQL Server 2016 and SQL Server 2017, and SQL Server 2019 supports older versions of TLS. SQL Server 2019 RTM is shipped with TLS 1.2 support, and no other update or fix is required to enable TLS 1.2 support.

TLS 1.2 being published in 2008 would then have an expected life of 22years to 2023 however we expect it to be longer than this. One reason to change version is vulnerabilities and TLS1. 2 has a lot of vulnerabilities caused by the older cryptographic algorithms that it still supports for compatibility reasons.

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.

SQL Server 2016 and SQL Server 2017 support TLS protocol versions 1.0, 1.1, and 1.2 by default on Windows Server 2016 and Windows Server 2019. No changes are necessary on the SQL servers in your SharePoint farm to enable TLS 1.1 or TLS 1.2 support.

According to this documentation by default TLS 1.0, 1.1 and 1.2 are enabled in Windows Server 2019. TLS 1.3 is only supported in Server 2022 and newer versions.

Click Start menu, either in the Run box or the Search box, type regedit and press Enter. The Registry Editor window should be opened. Check if the subkey of TLS v1. 2 is enabled for both server and client.

How to test if TLS 1.2 is enabled? ›

-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.

TLS 1.2 is enabled by default at the operating system level. Once you ensure that the . NET registry values are set to enable TLS 1.2 and verify the environment is properly utilizing TLS 1.2 on the network, you may want to edit the SChannel\Protocols registry key to disable the older, less secure protocols.

Microsoft's documentation has TLS 1.2 enabled by default in Win 11 / Windows Server 2019.

0, 1.1 and 1.2 both enabled on server by default. You can get this information from Microsoft Learn. You can check it from control panel. If you still want to check it from the registry, it may difficult to check because the registry is more used to disable a certain TLS version.

TLS 1.2 is enabled by default on Windows 10, version 1507+ and Windows Server 2012+. If you want to verify this, the easiest would be to create a PowerShell script that checks the Windows registry setting over here: HKLM SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols.

TLS protocol version support

For more information, see TLS 1.0 and TLS 1.1 deprecation in Windows. TLS 1.3 is supported starting in Windows 11 and Windows Server 2022. Enabling TLS 1.3 on earlier versions of Windows is not a safe system configuration.

-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.

The most recent, TLS 1.3, was released in August 2018. The differences between TLS 1.2 and 1.3 are extensive and significant, offering improvements in both performance and security.
