Hello!

Thanks for your work! Suggest to develop project little bit further:
To hide 3 or more secrets under one QR-code, where each password response\decrypt for different secred and it's impossible to proof there something more than just 1 secret in it... LIke in library here ->

https://github.com/sunknudsen/blockcrypt + https://github.com/sunknudsen/blockcrypt/blob/master/src/index.ts

I'm bad in coding but i could help with translation to few languages and making logo

Cheers!
