Security protocol TLS 1.2 in Dynamics NAV 2013

MrJanMrJan Posts: 2Member
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
Jan

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

    @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.
