Thank you very much @SFR10 for your additional input with very easy to understand steps for those who want to apply this method in the app.
Can I add a picture to those steps?
If you can, maybe tomorrow I will add it.
You're very welcome... Sure, but I forgot to mention something so please insert a sub-bullet for #5: There are three ways to get the 256 bits
[coin flip, dice and icosahedron] and if you don't provide enough entropy, it'd use its RNG to get the remaining bytes for you.
