Looks like a fairly sensible impl, a few points though:

• It would be good to add an isSecure() method (or something) to Connection so you can do the check without the tight coupling of instanceof
• It would be good to be able to specify which of the STREAM_CRYPTO_METHOD_*_SERVER constants is used (this would be simple enough via the shiny new $context arg)
• (I'm sure you're already on top of this one in some way) there should be an error event emitted in the case of failure

Do not forget to update http client too

This PR seems like a good starting point, thanks @cboden!

This PR has been WIP for quite some time now and things have changed considerably since then :-)

React now consists of individual components that are maintained individually. Supporting server-side SSL/TLS is now related to the react/socket component.

As such, I've just filed a new ticket reactphp/socket#24 to keep track of this, so I suppose it makes sense to focus our SSL/TLS related efforts on this component.
