ive done some more digging around on this and i... am dubious that it can be decrypted. based off the contents of the apk im lead to believe that crk uses a third party source called appsealing to encrypt their data--which uses aes-265 encryption. youre not going to be able to brute force it, and aes is designed in a way to stop people from guessing keys. you could try and track the apps traffic or dump its memory + see if you can glean anything from the code but appsealing says they do... something to prevent that. its a bit over my head to test it myself. for some reason, devsis really didnt want anyone getting into these files. maybe that makes sense with the recent nft announcements
its possible earlier versions of the apk dont have this same level of encryption, but i cant be sure, i havent been able to obtain a working .apk/.obb
