Hello!

Need help with saves of the game Disney Dreamlight Valley.

If I understand correctly all data are in profile.json, also there is a file keychain.json, perhaps it is somehow connected with encryption.

Initially my goal was to see if it was possible to manage some game quests through a save file. But as it turned out to read it is not so easy:)

 

I attach an archive with my files, there are only 2 files in it, because the rest of them do not play any role for sure:

steam_default_r.zip

 

the structure of the game profile folder is as follows:

Yep, definitely encrypted. Nothing can be done here without debugging game's code.

I spent some time digging into this. The game stores the JSON in a ZIP entry named profile and then encrypts the archive using AES-256 in ECB mode with PKCS#7 padding.

You can read the technical analysis here.

Use the attached Python script as follows:

python -m pip install cryptography

python .\ddv_profile.py --decrypt .\profile.json .\profile_decrypted.json
python .\ddv_profile.py --encrypt .\profile_decrypted.json .\profile.json

ddv_profile.py
