Ahhhh!!!! I get you now lol 
You got me scared for a bit.. I was like OH NO!! not another security issue!! ;) But to make the answer clearer . Ruffle does not convert flash to HTML5... At ALL!!! it just allows you to view the flash file... I have to recreate them from scratch in HTML5. So no quick fix! But if someone is desperate to get their flash file but can't view them, that's the alternative.
