I based the example on the boost example (http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/example/cpp03/ssl/server.cpp), which put the method in a class (which is why the this was there). I could change it to something like this:

std::stringpassword_callback(std::size_t max_length, boost::asio::ssl::context_base::password_purpose purpose) {returnstd::string("test");}...context_.set_password_callback(password_callback);

To get the same functionality. I think that might be better?

I think it's best to have an example of the SSL server that you can build/test locally that's also part of the project. If you put something in lib/network/example along in this pull request, then reflect what the code actually looks like here.

I'll create an example based on my local server setup. I'll add it to the pull request, change the documentation and get back to you.
Thanks for the help!

Awesome, thanks@jellevdd for doing this!

@deanberris I've added a basic example based one of the existing async server examples. I've added a self-signed private key/certificate (valid for 10 years) to the example to simplify testing.
The documentation has been updated to mirror the example.
While testing basic ssl I've also noticed a small bug which was causing a warning to be thrown during shutdown of the socket when using basic ssl (I tested using mutual authentication which did not cause any issues). I've added the fix to the shutdown as well.

@jellevdd Thanks! This looksawesome. :)

Thank you very much for doing this. I'm merging this in, and if you can make an announcement to the mailing list, that would be greatly appreciated too. Having testers give this a go would be great for the project and hopefully we can get a new release rolled out soon after.
