SSL communication - hrebik - 03.02.2016
Hello,
My LogicMachine communicates with second device via TCP (outgoing from LogicMachine) and HTTP (incoming to LogicMachine) protocols , I want to secure them with SSL. I can ensure SSL certificate with JavaScript in second device.
When I create socket it runs this code:
local host, port = "IP address", portNO.
local socket = require("socket")
local tcp = assert(socket.tcp())
tcp:connect(host, port)
--some code here
tcp:send(value)
tcp:close()
this is SSL unsecured, when I want to send value to server,
and when I receive data I create socket and send feedback data via
socket:send(value);
Is there some simple way to secure this communication with SSL in LogicMachine's Lua script?
Thank you!

Have a look here for HTTPS requests:
http://openrb.com/docs/lua.htm#ssl.https.request
If you need SSL for raw sockets, I can provide an example later.

Thank you!
And I need also SSL for raw socket and copas.
Thanks alot

For now we only have support for SSL/TLS in client mode, here's a short example. If handshake fails, try setting proto to tlsv1.
Code:
require('socket')
require('ssl')
host = '127.0.0.1'
port = '443'
proto = 'tlsv12' -- can also be 'tlsv1' or 'tlsv11'
sock = socket.tcp()
res, err = sock:connect(host, port)
if res then
sock = ssl.wrap(sock, proto)
res, err = sock:dohandshake()
if res then
...
else
log('Handshake failed', err)
end
else
log('Connect failed', err)
end
sock:close()RE: SSL communication - hrebik - 05.02.2016

Thank you,
Is it possible to make it also for server mode (copas)?

Give us some time to finish the next FW release, then we'll update the SSL library with server part
