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.
General help
Adobe Flash not being supported on browsers
