@adrienthebo how about pulling this whole test and unwrap chunk (with it's comment) out as a method to call out what's going on.  And if we could add a reference to http://tools.ietf.org/html/rfc2985#ref-10 5.4.2 and http://tools.ietf.org/html/rfc5280 4.1 in the comment (explaining the structure) that would help next time we come back to stab our eyes with this.
