Archeage 2.0

Post by ploxasarus »

I am having a hard time decompressing the main database file (compact.sqlite)
It is rather simple to get this file encrytion key, but since 2.0 they compressed the database file and I can't find a way to de-compress it. Maybe one of you could help us?
Original file size should be around ~150mb
Thanks

It's still encrypted in my opinion, the last 3 unaligned bytes are in not encrypted.

Previously, the key was hidden in archeage.exe - it look like it's no longer there ( I don't know much about this, I am just guessing, as the decrypter we previously used no longer find it)

They changed encryption and format.

1) Sqlite file encrypted with double rounds by AES with small modification + XOR. You can't find aes key and xor key because it generated from 4 secret constants.
2) DataBase is a zip archive. Inside it is divided to 8 chunks. (see screenshot)
3) DataBase for now not SQLite format 3 - now it binary data with custom structure

So there is no "method" to "recrypt" it.

Thanks
