@jlai.luAlright thank you for your reply, I'll think about it :) maybe having a vérification that can be done in any computer and any amount of time is just not possible for my use case
Indeed, I didn't think of that. And would it be possible to allow only one check and destroy/make the information of B unusable after this check?
Thank you for your reply!
I would like to avoid using photoshop if something else is available, but thank you for the proposition!
I tried it but it only allows very simple stuff, for instance its not possible to insert images :( but I guess i'll begin with this
