B4J Question SSL and SHA1 SHA2 RSA DSA

Swissmade · Mar 3, 2017

Hi All,
I have a IO-Box that can create a Self-signed SSL certificate.
The IO-Box uses a XPort-Pro from Lantronics to connect to the Network.
Now I like to connect to this with a TCPSocket.
To Connect I like to use socket.InitializeSSL.
How can I tell the Socket to accept a Self-signed certificate.

I have seen this https://www.b4x.com/android/forum/threads/network-v1-50-adds-support-for-ssl-sockets.55871/
But I don't see how to give a Self-signed certificate
Many thanks to helping me out here.

You will need to create a keystore with the server certificate.

See the answer here on the steps required: http://stackoverflow.com/questions/...-existing-certificate-abc-crt-and-abc-key-fil

I have a sslcert.pem and sslkey.pem upload to the x-port and working.
This certificates I have build with OpenSSL.
How can I use this with the Socket.InitializeSSL.

Please help.
Thanks

Were you able to create a keystore file?

No Not yet
I have made a keystore like this.
openssl pkcs12 -export -name servercert -in sslcert.pem -inkey sslkey.pem -out myp12keystore.p12

Bad is, that I still can not connect to the Xport.

Thanks Erel for your help.

Something Wrong with connection

Source I us to connect

B4X:

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private Sock As Socket
    Private AsyncSock As AsyncStreams
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
    Dim in As InputStream = File.OpenInput(File.DirAssets, "Entrada-keystore.p12")
    Sock.InitializeSSL("Sock", in, "Born to be wild")
    setprotocol
'    Sock.Initialize("Sock")
    Sock.Connect("192.168.1.205", 10001, 5000)
End Sub

private Sub Sock_Connected (Successful As Boolean)
    If Successful = True Then
        Log("Whe have Connection")
    Else
        Log("Something Wrong with connection")       
    End If
   
End Sub

Private Sub setprotocol
    Dim r As Reflector
    r.Target = Sock 'socket variable
    r.Target = r.GetField("socket")

You should convert to to a keystore. It will not work in other formats.

I assume that I have done this with this command.
openssl pkcs12 -export -name servercert -in sslcert.pem -inkey sslkey.pem -out Entrada-keystore.p12

See this thread: http://stackoverflow.com/questions/...-existing-certificate-abc-crt-and-abc-key-fil

You need to use Keytool to import it to a keystore.

Ok I see I mist one step
Thanks Erel

Bad not working also with Keystore file.

Swissmade · Mar 10, 2017

Still not working,
Steps I have done.
With OpenSSL
First I create a Cert and Private key file.
Then I Create a keypair with password openssl pkcs12 -export -name servercert -in sslcert.pem -inkey sslkey.pem -out Entrada-keystore.p12
Last I create a keystore file from the p.12 file with keytool.

The certificate and Private key working in the XPort.
I don't know what's still going wrong here.
Still get a javax.net.ssl.SSLHandshakeException
