Crypted Backup

Hello,

I have an issue trying to parse the .backup file.
Indeed, in January I succeeded in parsing the "1 to 1" table to make my own queries through a reporting tool. The task was pretty hard though...
But since yesterday (did not reopened it since January...) I tried to open a new .backup file and amazingly it was crypted!! I mean I cannot open it clearly and I can't read the datas.
--> I would try to understand how I could avoid this file from being crypted.
Or is this a choice to force csv and qif exports ? These two files do not retrieve a lot of datas such as attributes, splits, budget properties, scheduled expenses...

Thanks in advance for your answers.
