[feature] Working SSL

[lgg2]

Hello,

I have adapted the openssl example to wsServer and... works. Yes I have a working wss solution. But first I must any dummy to confirm this.

Place a cert.pem and a key.pem in place, open the port 8443 and try with the echo example.

Only 2 new functions (may be placed in one), a SSL_accept and change send/recv to SSL alternatives. No more needed.

Hi @lgg2,
Wow, that's awesome, can you point to me that source, so I can try and test?
May I assume is this one right here? lgg2@e8733d2

If so, that's nice, I wouldn't expected to be that simple, since OpenSSL is too much complex, and etc. Please go ahead and send a PR, just a few notes first:

• It looks like the code has been reformatted, which I usually don't like... since it breaks the commit history a bit when you do a 'blame'. Did you use clang-format by any chance? If so, that's fine.

• I would like this to be added conditionally so that wsServer still works in an environment without OpenSSL, something like: #ifdef ENABLE_OPENSSL.

• In your code I didn't see any changes to the build scripts, like in the Makefile or CMakeLists.txt.

In general, I would like to receive these changes so that I can test them right away with a make or CFLAGS="-DENABLE_OPENSSL=yes" make. If you have trouble with this, you can send it as is.

Hello,

Sorry for the reformat. It has been thing of VScode. I will re-do the thing.

And yes, I will place the conditional include. Also, the only change in Makefile it is the addition of -lssl and -lcrypto

I will do it tomorrow.
