Like @Lordoftheshard 2 said use hypophosphoric acid for an easier and quicker method if you can find it.
Forget match strike pads if you can't get red easily, order these. https://www.aliexpress.com/w/wholes...f=auto_suggest&spm=a2g0n.productlist.header.0
Moisten slightly with acetone and let it soak a little, scrape the phosphorus off.
As for HCl generation, be careful with foil it can get violent. Keep going with non iodized salt and adding hydrochloric dropwise in a sealed vessel with a hose out the top. If you don't have lab equipment a plastic coke bottle with a small tube through the lid will do.

How do you go about getting the red p off the paper? Can you just scrape it??

Soak in acetone long enough - about 30 minutes - and it will basically fall off by itself, you may have to rub it a little. You should not have to put in effort to 'scrape' it off. Just wash it and filter to collect clean RP. Then cook RP on low heat in %20 NaOH solution for about an hour. Wash, filter and dry RP. After drying it will be ready to be reacted with I2. If you can get sodium hypophosphite to make your phosphorous acid it is much better for this reaction than RP.

The sodium hypophosphite -> hypophosphorous acid <=> red phosphorous + I2 = Hydriodic acid. It is what Uncle Fester talks about when he goes on about the electroless nickel plating. It is sold as the 'C component'. Or 'R component' for replenisher, I believe. You may be correct I am not sure exactly how you mean. You will have to do a little research or keep asking.
