Hello Dev, welcome to this comprehensive guide on how to check TLS version on Windows Server. Transport Layer Security (TLS) is a cryptographic protocol that secures communication over computer networks. TLS is widely used to secure HTTP traffic between a web server and a client browser. In this guide, we will discuss the various ways to check the TLS version on Windows Server.
Method 1: Using the Registry Editor
The registry editor is a powerful tool used to view and modify the Windows registry. The Windows registry contains configuration settings for the operating system and installed applications. You can use the registry editor to check the TLS version on Windows Server. Follow the steps below:
- Press the “Windows + R” key combination to open the “Run” dialog box.
- Type “regedit” in the text field and click “OK”. This will open the registry editor.
- Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols”.
- Under the “Protocols” folder, you will see folders for different protocols. Look for the folder corresponding to the TLS version you want to check. For example, if you want to check TLS 1.2, look for the folder named “TLS 1.2”.
- If the folder exists, it means that TLS 1.2 is enabled on your Windows Server. If the folder does not exist, it means that TLS 1.2 is not enabled.
You can repeat the above steps for other TLS versions to check their status on your Windows Server.
Method 2: Using the Internet Information Services (IIS) Manager
The Internet Information Services (IIS) Manager is a web server management tool that is included with Windows Server. You can use the IIS Manager to check the TLS version on your Windows Server. Follow the steps below:
- Open the IIS Manager by clicking the “Start” button and typing “IIS” in the search box. Click the “Internet Information Services (IIS) Manager” option.
- Expand the server node in the left pane and select the “Server Certificates” option.
- Select the certificate you want to check the TLS version for.
- Click the “Bindings” option on the right pane.
- Look for the “Protocol” column and check the TLS version for each binding.
You can repeat the above steps for other certificates to check their TLS version on your Windows Server.
Method 3: Using PowerShell
PowerShell is a powerful command-line tool that is included with Windows Server. You can use PowerShell to check the TLS version on your Windows Server. Follow the steps below:
- Open PowerShell by clicking the “Start” button and typing “PowerShell” in the search box. Click the “Windows PowerShell” option.
- Type the following command:
Get-TlsCipherSuite | Select-Object Name, CipherType, Protocols
- Press “Enter”. This will display a list of all the TLS cipher suites and the protocols they support.
- Look for the TLS version you want to check and verify if it is supported by any of the cipher suites.
You can run the above command for other TLS versions to check their status on your Windows Server.
