Are there NET implementation of TLS 1 2

Question

Since I just discovered that RFC 5425 requires TLS 1 2 to be used  and that  NET doesn t yet support it  I wonder if there are any implementation  possibly open source  of TLS 1 2 protocol  as defined in RFC 5246

Just download this registry key and run it  It will add the necessary key to the  NET framework registry  You can have more info at this link  Search for  Option 2  in   NET 4 5 to 4 5 2    The reg file appends the following to the Registry    HKEY LOCAL MACHINE SOFTWARE Microsoft  NETFramework v4 0 30319   SchUseStrongCrypto  dword 00000001   HKEY LOCAL MACHINE SOFTWARE Wow6432Node Microsoft  NETFramework v4 0 30319   SchUseStrongCrypto  dword 00000001   This is the part of the page that is useful in case it goes broken              enable TLS 1 2 by default without modifying the source code by setting the SchUseStrongCrypto DWORD value in the following two registry keys to 1  creating them if they don t exist   HKEY LOCAL MACHINE SOFTWARE Microsoft NETFramework v4 0 30319  and  HKEY LOCAL MACHINE SOFTWARE Wow6432Node Microsoft NETFramework v4 0 30319   Although the version number in those registry keys is 4 0 30319  the  NET 4 5  4 5 1  and 4 5 2 frameworks also use these values  Those registry keys  however  will enable TLS 1 2 by default in all installed  NET 4 0  4 5  4 5 1  and 4 5 2 applications on that system  It is thus advisable to test this change before deploying it to your production servers  This is also available as a registry import file  These registry values  however  will not affect  NET applications that set the System Net ServicePointManager SecurityProtocol value

If you are dealing with older versions of  NET Framework  then support for TLS 1 2 is available in our SecureBlackbox product in both client and server components  SecureBlackbox contains its own implementation of all algorithms  so it doesn t matter which version of  NET-based framework you use  including  NET CF  - you ll have TLS 1 2 with the latest additions in all cases    Please note that SecureBlackbox wont magically add TLS 1 2 to framework classes - instead you need to use SecureBlackbox classes and components explicitly

I fixed my problem by switching to the latest  Net Framework  So your target Framework sets your Security Protocol    when you have this in Web config    lt system web gt     lt httpRuntime targetFramework  4 5   gt   lt  system web gt    you will get this by default    ServicePointManager SecurityProtocol   Ssl3   Tls   when you have this in Web config   lt system web gt     lt httpRuntime targetFramework  4 6 1   gt   lt  system web gt    you will get this by default    ServicePointManager SecurityProtocol   Tls12   Tls11   Tls

You can enable TLS 1 2 in IIS by following these instructions  I presume this would be sufficient if you have an ASP NET-based application that runs on top of IIS  although it looks like it does not really meet your needs

Yes  though you have to turn on TLS 1 2 manually at System Net ServicePointManager SecurityProtocol  System Net ServicePointManager SecurityProtocol   SecurityProtocolType Tls12   SecurityProtocolType Tls11   SecurityProtocolType Tls     comparable to modern browsers var response   WebRequest Create  https   www howsmyssl com    GetResponse    var body   new StreamReader response GetResponseStream    ReadToEnd         Your client is using TLS 1 2  the most modern version of the encryption protocol     Out the box  WebRequest will use TLS 1 0 or SSL 3      Your client is using               TLS 1 0  which is very old  possibly susceptible               to the BEAST attack  and doesn t have the best cipher               suites available on it  Additions like AES-GCM  and SHA256               to replace MD5-SHA-1 are unavailable to a TLS 1 0 client               as well as many more modern cipher suites

You can make use of the SchUseStrongCrypto registry setting to require all  NET applications to use TLS 1 2 instead of 1 0 by default   Windows Registry Editor Version 5 00   HKEY LOCAL MACHINE SOFTWARE Microsoft  NETFramework v4 0 30319   SchUseStrongCrypto  dword 00000001   HKEY LOCAL MACHINE SOFTWARE Wow6432Node Microsoft  NETFramework v4 0 30319   SchUseStrongCrypto  dword 00000001
