Amazon S3 Upload error SSL certificate issues

I'm trying to test Laravel Amazon S3 on my localhost but keep getting the same error:

S3Exception in WrappedHttpHandler.php line 192:
Error executing "ListObjects" on "http://ift.tt/2aDdlwZ"; AWS HTTP error: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://ift.tt/1mgwZgQ)
