Security protocol TLS 1.2 in Dynamics NAV 2013

MrJan

Hi out there!

I am trying to increase a web requests security protocol in order to access a web service which is requiring TLS 1.2.
My default SSL is not accepted.

The request is send from Dynamics NAV 2013 (7.00).

I have of course searched for a solution to this problem elsewhere. One single line should be enough:
ServicePointManager.SecurityProtocol := 3072;

This however does not grant me access to the server.


HttpWebRequest := WebRequest.Create(txtURLiLG);

ServicePointManager.SecurityProtocol := 3072; // 3072 = Tls12 (TLS 1.2)

HttpWebRequest.Timeout := 600000; // 10 minutes
HttpWebRequest.ReadWriteTimeout := 600000; // 10 minutes

HttpWebRequest.ContentType := 'text/xml;charset=utf-8';
HttpWebRequest.Method := 'POST';
SystemTextUTF8Encoding := SystemTextUTF8Encoding.UTF8Encoding();
Bytes := SystemTextUTF8Encoding.GetBytes(XMLDoc.InnerXml);
HttpWebRequest.ContentLength := Bytes.Length;
RequestStream := HttpWebRequest.GetRequestStream();
RequestStream.Write(Bytes, 0, Bytes.Length);
RequestStream.Close;


Do any of you have a hint setting securety protocol to TLS 1.2 in Dynamics NAV?

Thanks.

Best regards

check if .net framework 4.5 is installed. if not install it.
.net 4.0 does not support TLS 1.2.

MrJan

Thanks archer89.
The .net framework 4.5 is already installed.

Best regards

@MrJan Try this:

ServicePointManager=System.Net.ServicePointManager
SecurityProtocolType=System.Net.SecurityProtocolType

ServicePointManager.SecurityProtocol := SecurityProtocolType.Tls12;

Hi Agannalo,

I need a solution for Dynamics NAV 2016. The members you're showing above are not available as DotNet-Types to create variables. .NET Framework 4.5 is installed.

Sorry to wake old thread, but please find below resolution (As Agannalo previously stated). This worked for me with NAV2017. I just hope the customers would update at last.

First create a global .NET variable for System.Net.ServicePointManager, and then call it with

ServicePointManager.SecurityProtocol := SecurityProtocolType.Tls12;

Cannot find System.Net.ServicePointManager in .NET variable. I've 4.8 .NET framework installed..

Hello weneed,
you can find it in the System Assembly.

See here:
https://docs.microsoft.com/de-de/dotnet/api/system.net.servicepointmanager?view=netframework-4.8

In the top left Corner you can change the Version.

If you input the following string into the subtype it should work:

System.Net.ServicePointManager.'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Thanks so much!!
