If I take my hat of RFC pedantic : THIS IS A SIN, padding is mandatory.

Well RFC pedantic might point out that all = in excess MAY be ignored (which decoders often accept (but not always)).

I often add "===" after a b64encoded string when I am in the mood for seeing the world burn. And it's fun.

I am not convinced by the rationale of the mandatory padding in the RFC in the first place to be honest.
