Android Question SSL Websocket client

[LucaMs]

Trying to connecting to my websocket server:

closed javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x63a133b0: Failure in SSL library, usually a protocol error
error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:741 0x61803166:0x00000000)

Libraries used:
client: WebSocket 2.00
server: jServer 2.80

The server starts and it is reachable (ping). I suppose that if the server SslConfiguration (and the keyvaluestore I created) were incorrect the server would not start/work, correct?

 

[Erel]

Are you sure that you are connecting to the SSL port?

 

[LucaMs]

Yes, it was an old project I modified just to use SSL, then same port.

Also, if I had set the wrong port...

The server starts and it is reachable (ping)

 

[Erel]

My guess is that the port is wrong.

 

[LucaMs]

Unfortunately not.

client b4a:
Public Const ServerURL As String = "wss://xxxxxxxxx:52650/xxxx"

server b4j:
ConfigureSSL(52650)

 

[Erel]

You should provide more information.

Example of a working ssl connection using the libraries you mentioned:

Dim ws As WebSocket
ws.Initialize("ws")
ws.Connect("wss://b4x.com:51041/smiley/ws")
Wait For ws_Connected
Log("connected")
Wait For ws_TextMessage (Message As String)
Log(Message)

 

[LucaMs]

You should provide more information.

I don't know what informations.

My code is very similar to yours.

Just one thing: creating the keyvaluestore I had to use, temporarily, an IP address; but I think that if this were the problem I would not reach the server (I pinged the server from an online service).

The old project works perfectly if I do not use SSL.

I found this:
https://stackoverflow.com/questions...on-javax-net-ssl-sslprotocolexception-ssl-han

where they say that there are problems with Android < 4.4 but I'm using Android 4.4.2

 

[LucaMs]

Tried this code in my app:

Private Sub TryToConnect
'    wsh.Initialize(Me, "wsh")
'    wsh.ws.Connect(Main.ServerURL)

    NewWS.Initialize("NewWs")
    NewWS.Connect("wss://b4x.com:51041/smiley/ws")
    Wait For NewWs_Connected
    Log("connected here")
    Wait For NewWs_TextMessage (Message As String)
    Log(Message)
    ExitApplication
End Sub

No logs (TryToConnect starts, of course)

This works (browser):

@LucaMs
To make the ranking of your game safe, use FireBase and not the SSL protocol that in some way can be sniffed by Hacker and used to induce false scores.

With Firebase the App that sends will be authenticated.
With SSL you can not identify the genuineness of the sending app. This is the main problem for security.

Better that you talk to an expert about it rather than improvise solutions

 

[Erel]

Please try the attached project and post the logs.

Please try the attached project and post the logs.

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Connecting
** Activity (main) Resume **

 

[Erel]

Add this sub:

Sub ws_Closed (Reason As String)
   Log("error: " & Reason)
End Sub

Is it raised? Are you testing it on a real device?

I'm trying this for A9, but it's the same.

Anyway, I will not use only SSL, I think.

Thank you

Add this sub:

Sub ws_Closed (Reason As String)
   Log("error: " & Reason)
End Sub

Added.

Real device (Android 4.4.2) and, now, in release mode.

[Star-Dust]

But the @Erel code is very useful for me, thank you

 

[LucaMs]

I know what the bug is: I AM THE BUG! Every day at least one abnormal problem!




This is LUCK

 

[LucaMs]

It's the same log (Erel's code) using a different old device, Android 4.0.4.

 

[Erel]

I also get this error on an AVD running Android 4. Checking this...

 

[Erel]

You can try the attached project. It uses a Google service to update the security provider. It didn't work on the emulator (the ProviderInstaller failed).

The code is in the starter service.

 

[LucaMs]

It almost works, since connects, but after 2 seconds:

Spoiler: Log

*** Service (starter) Create ***
Installing security provider if needed...
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
Provider installed successfully
Connecting
connected
