Secure exchanges using only socket-io and web client (socket io js)

阅读更多关于 Secure exchanges using only socket-io and web client (socket io js)

问题 I created a SSL certificate with openssl on a debian 8 VM. So i have a single PEM file which contain my key and my certificate. I would like to know if it's possible to use a SSL certificate without https, express etc, simply by using a architecture with socket IO (server side) and socket IO client (client side). Server side : var fs = require("fs") , options = { key : fs.readFileSync('./test/apache.pem'), cert : fs.readFileSync('./test/apache.pem') } var io = require('socket.io').listen

问题 I should have paid more attention to my classes that covered security. I'm quite confused about something. To start, here's the background of what I'm trying to accomplish. I have a web service that I need to access. The web service is set up as HTTPS. The traffic between client and server is encrypted (this doesn't have to do with authentication). I'm interacting with the web service via cURL and PHP. I've gotten an example to work locally over HTTP and I'm fairly confident I'm on the right

I have looked at Reading and writing rsa keys to a pem file in C and openssl pem. But i am not working with RSA keys. I suspect my task is much simpler like create pem from base64 but not much help. PS: This key will be used to encrypt a self signed digital certificate. EDIT: looking around more i found that i could use bio
