Guzzle: How to Change the Default Handler From Curl to PHP Streams

I have been having problems getting curl to interact with a server that uses sslv3 with an ssl certificate and private,

I could connect using openssl, and from Java but not through curl (think its a curl specific problem).

How can I change guzzles handler from curl to php streams and where do I set the environment variables..?

Is there a Laravel specific guzzle.?? since guzzle is a general php library.

Thanks
