Additional context

[ElDavoo]

Your backup is already decrypted.

[gekigek99]

Could you add a notification saying that in the script?

(And also add in the readme that to read that file you need sqlite to read the cript15 file)

(Spent 2h understanding that cause online it's full of paytouse bullshit)

[ElDavoo]

[E] The database file is not encrypted.

It's there...

[gekigek99]

Yeah right infact that was the line that made me suspect of that.

I just think it's a very important info which is mixed with all the other errors (which i think shouldnt even be there if the file is already decrypted)

Like, the logs are telling me to report a bug ahah :)

...let alone the fact that you have to use the force parameter to see it.
