If you are using a Windows client to access your Azure Stack Edge Pro device, you are required to configure TLS 1.2 on your client. This article provides resources and guidelines to configure TLS 1.2 on your Windows client.

The guidelines provided here are based on testing performed on a client running Windows Server 2016.

Configure TLS 1.2 for current PowerShell session

Do the following steps to configure TLS 1.2 on your client.

  1. Run PowerShell as administrator.

  2. To set TLS 1.2 for the current PowerShell session, type:

    $TLS12Protocol = [System.Net.SecurityProtocolType] 'Ssl3 , Tls12'
    [System.Net.ServicePointManager]::SecurityProtocol = $TLS12Protocol
    

Configure TLS 1.2 on client

If you want to set system-wide TLS 1.2 for your environment, follow the guidelines in these documents:

  • General- how to enable TLS 1.2

  • How to enable TLS 1.2 on clients

  • How to enable TLS 1.2 on the site servers and remote site systems

  • Protocols in TLS/SSL (Schannel SSP)

  • Cipher Suites: Specifically Configuring TLS Cipher Suite Order Make sure that you list your current cipher suites and prepend any missing from the following list:

    • TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
    • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
    • TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
    • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384

    You can also add these cipher suites by directly editing the registry settings.

    New-ItemProperty -Path "$HklmSoftwarePath\Policies\Microsoft\Cryptography\Configuration\SSL\00010002" -Name "Functions"  -PropertyType String -Value ("TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384")
    
  • How to set elliptical curves

    Make sure that you list your current elliptical curves and prepend any missing from the following list:

    • P-256
    • P-384

    You can also add these elliptical curves by directly editing the registry settings.

    New-ItemProperty -Path "$HklmSoftwarePath\Policies\Microsoft\Cryptography\Configuration\SSL\00010002" -Name "EccCurves" -PropertyType MultiString -Value @("NistP256", "NistP384")
