1 year ago Hi, i had similar problems with TLS 1.3 and compression on Android and iOS. Here is my implementation:
HttpClient result = null;
if(Device.RuntimePlatform == Device.Android) {
try {
var handler = DependencyService.Get<HttpClientHandler>();
if(handler != null) {
handler.AutomaticDecompression = DecompressionMethods.GZip;
result = new HttpClient(handler);
}
else
result = new HttpClient();
}
catch {
if(result == null) {
result = new HttpClient();
}
}
}
else {
result = new HttpClient();
result.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("gzip"));
}Perhaps it helps you.
Description
In my Xamarin forms iOS project I have set "HttpClient Implementation" as "NSUrlSession (iOS 7+)" and in code we create HttpClient as below:
HttpClient httpClient = new HttpClient(new HttpClientHandler() { AllowAutoRedirect = true, MaxAutomaticRedirections = 100, AutomaticDecompression = DecompressionMethods.GZip })
But this doesn't work with TLS 1.3 server in the blog here it has been mentioned that "NSUrlSession (iOS 7+) supports TLS 1.2+. Below is the link to the blog:
https://devblogs.microsoft.com/xamarin/securing-network-traffic-with-tls-1-2/
The exception I am getting is as mentioned below:
{System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception. ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception. ---> Mono.Security.Interface.TlsException: Unknown Secure Transport error `PeerProtocolVersion'.
So, please let me know if TLS 1.3 is supported in Xamarin forms iOS and if yes then how do I fix this issue.
Steps to Reproduce
Expected Behavior
The application should work without any error with TLS 1.3.
Actual Behavior
The application doesn't work with TLS 1.3 server.
