Ssl try

[lgg2]

Hello,

Included Openssl initial/basic support.

Compile with CFLAGS+="-DENABLE_OPENSSL=yes" make

Only echo example changed to test. Use wss option and place the correct url and port in the Server input box.

This add 2 new (internal) functions that maybe join into only one and change the send/recv for the Openssl equivalents.

It must be a valid cert.pem and key.pem into cert directory. If not, the browser may refuse to accept the connection (with selfsigned certs for localhost I have problems).

Be free to refactor the added parts. Are easy to understand how works. You know better wsServer part.

All info extracted from Openssl Wiki example.

Hi @lgg2,
Thank you for your PR, as you might note, this is a feature I wanted for a long time, but I always post-poned, until now... so thank you for addressing it.

Having native support for SSL, although via an additional dependency, addresses issues like #88 and #77, so definitely a wanted feature.

That said, there are some things that I want to change on this PR, so I'll probably merge it on a different branch, work on that, and later merge everything to master.

For the time being, there also some things I must point out:

• I still see some reformating throughout all the code, which makes hard to understand your real changes.
• The other ones I'll comment right below.

There is also build issues due to the lack of the library, but I'll tackle that, so no need to worry about it.

Hello,

I will try to make the needed correct changes before pull again.

About the activation of "wss" mode: to include 2 pointers to string into struct ws_server for the "cert" and "key". If the are not NULL and valid, then work in "wss" mode, else "ws".

Also need the inclusion of SSL *ssl pointer in struct ws_connection, SSL_ctx *ssl_ctx and an additional function (among some few lines more) in the ws.c file.

In that way, there is no need to touch any code that use the wsServer.

I will try to pull again when done.
