I have a reliable (if a bit ugly) implementation in under 3kb of sparse PHP OOP code. Yes it took a few hours to iron out the last kinks, and one extra refactor to free up a mistakenly bound variable. It might have helped that it was the first version I implemented, thus no need to match impedance of older interface.
On the plus side, the signing is designed as self-contained, and neither implementation nor API calls spill to too many parts of request handling.
>you have to read the doc a dozen times before you can successfully implement it
Very much so - it does require a small 'eureka' moment. It's hard to put your finger on what exactly makes it hard to get right the first time around. At the very least it is written from a somewhat peculiar viewpoint.
Fortunately the primitives used are common enough to be available in typical standard libraries.
Don't be overly discouraged :-)
