Was reading HTTPS workflow and would like to understand more about it.
Client ---> Malicious Server (instead of actual server)
When Client connects to server there can be possibility that it connects to malicious server and that server represents the certificate on behalf of Actual Server, how client knows whether its genuine server or not?

Pass connected SSL Socket to another Process
(1 answer)
Closed 5 years ago.
The first process will receive and send some data (to complete the authentication) after accept a sslsocket, then send the sslsocket to another process.
I know that multiprocessing.reduction.send_handle can send socket, but it didn't work with sslsocket.
Please help.
This is not possible.
SSL sockets in Python are implemented using OpenSSL. For each SSL socket in python there is a user space state managed by OpenSSL. Transferring a SSL socket to another process would need this internal SSL state to be transferred too. But, Python has no direct access to this state because it only uses the OpenSSL library with the Libraries API and thus can not transfer it.

Where can I find a good tutorial on iPhone/Objective-C multithreading? [closed]

I am working on writing a simple Redis client application in Objective-C. In order to communicate with Redis on my server I need to SSH into the server and then open a TCP socket to send data back and forth. I am trying to follow an example from libssh2.org, direct_tcpip.c and I have gotten it to work well. I can run the code, and it will say:
Waiting for TCP connection on... 0.0.0.0:6379
So I then try to communicate with it using telnet:
telnet 0.0.0.0 6379
I can successfully connect and interact with Redis this way, YES!
Now the next step is for me to be able to programmatically talk to the server and send it commands from the UI of my app, but the program gets blocked when I call accept() and is stuck waiting for a connection to come in. That's a problem because I need to programmatically connect TO it and I can't seem to figure out how to do that.
I tried calling libssh2_session_set_blocking(session, 0); before accept(), but that didn't seem to change anything.
My goal is to set up the forwarding so that my app can communicate with a remote Redis server as easily as possible and I am totally new to socket programming. I need an SSH tunnel because Redis does not have built-in security and it is recommended that you communicate with it internally.
Thank you to anyone who can point me in the right direction!
The comment posted by #Danack solved the problem for me. I am using a background thread to do the listening and now I am no longer blocked and connecting just fine.

How do I enable HTTP basic authentication to a Jetty server which runs as a service. I want this to be a server configuration regardless of the contexts that it runs (i.e. I don't want to have to modify the web.xml).
Maybe this answers your question: Jetty webserver security

SSL costs more bandwidth.
SSL costs processor cycles, both on the server and the client.
Both things cost loading/processing time.
