TLS 1.2

Hi guys, it looks like we have regression here.

Starting from version of Flash Player 26 the issue from this
thread is reproducible again.

At least for IE (win7) FlashPlayer 25 works perfectly with
TLS 1.2, but FlashPlayer 26 fails to connect with same symptoms.

With Chrome everything fine (all versions of Flash Player).

With FireFox it is also not working.

Can you verify why it is not working again?

Hi Chris,

We still not succeeded to communicate with server with SecureSocket on ActiveX and NPAPI flash plugins (PPAPI working fine).

Please confirm that TLS 1.2 connection supported on ALL plugin versions by SecureSocket.

Our current observation is that only PPAPI plugin and one used in win8/10 are support TLS 1.2.

TLS 1.0 supported by all.

1. IE is working fine on Win 10, FireFox only with old flash plugin (16)
2. We using SecureSocket in order to communicate to port 443 (first 843 with flash policy file).
3. Please see below simple application that trying to connect to TLS server that support TLS 1.1 and 1.2 only
4. On WIN 7 it is working on Chrome only; on WIN 8 - IE working, FireFox connection works only with old Flash version (16)

package

{

       import flash.display.Sprite;

       import flash.net.SecureSocket;

       import flash.text.TextField;

       import flash.events.Event;

       import flash.events.IOErrorEvent;

       import flash.events.SecurityErrorEvent;

       public class tls extends Sprite

       {

private var connection:SecureSocket = new SecureSocket();

private var tf:TextField = new TextField();

public function tls()

{

addChild(tf);

tf.x=0;

tf.width=1400;

connection.connect("<SomeDomain.com>",443);

connection.addEventListener(Event.CONNECT, onConnect);

connection.addEventListener(IOErrorEvent.IO_ERROR, onSocketError);

connection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSocketError);

}

private function onConnect(e:Event):void

{

tf.text = "CONNECTED";

}

private function onSocketError(e:Event):void

{

tf.text = "NOT CONNECTED:"+ e;

}

       }

}

. 

5.  Handshaking failing after CLIENT HELLO (server support TLS 1.1 and 1.2 only)

6.In Chrome CLIENT HELLO send with TLS 1.2 and connection successfully established

Hi,

Could you verify that TLS is working correctly in IE?  AIR uses these same settings, so enabling for IE should fix your problem.

Enabling TLS 1.1 and TLS 1.2 in Internet Explorer

Thanks,

Chris
