With this PR encryption and decryption are added to the flow (while uploading and downloading the files from the user personal area).

I faced one big issue with the encoding functions. They are using the TextEncoder (and TextDecoder) they are global in node js so there I so reason to import them from util. But this means we have no trace of them in the jest environment (jsdom).

I found different references on this point, I'll link here one of the solution suggested
