using (var client = new HttpClient())
{
var req = client.GetAsync("https://permid.org/1-55835312773?access-token=<token>&format=json-ld").Result;
Console.WriteLine(req.Content.ReadAsStringAsync().Result);
}
During this connection establishment only- We are getting below error message exception:
From my finding, it relates to the Cipher Suites used by permid.org. Refer to https://www.ssllabs.com/ssltest/analyze.html?d=permid.org, permid.org supports the following Cipher Suites for TLS 1.2.
However, It looks like Windows 7 doesn’t support these cipher suites (https://social.technet.microsoft.com/Forums/ie/en-US/d1a10844-18fb-4400-b649-60183c5f58c6/how-to-add-cipher-suite-to-windows-7-tlsrsawithaes128gcmsha256?forum=w7itprosecurity).
I found a solution on the StackOverflow.
If I use .NET Framework 4.5, the code looks like this:
using System;
using System.Net;
using System.Net.Http;
namespace ConsoleApp12
{
class Program
{
static void Main(string[] args)
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
using (var client = new HttpClient())
{
var req = client.GetAsync("https://permid.org/1-55835312773?access-token=<token>&format=json-ld").Result;
Console.WriteLine(req.Content.ReadAsStringAsync().Result);
}
}
}
}
