Accessing WDB cache files (QuestCache.wdb)

[Frosttall]

Has anyone found a method to access the encrypted data in QuestCache.wdb or reversed the latest structure of it?

The only unencrypted part is the header, which is displayed as following:

0,25152,881,25152,2,1,0,1,363,0,0,25126,3,0,30,0,0,0,0,0,524288,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,"","","","",0,0,0,0,0,0,0,0,76,0,0,0,0,3,0,0,"","","","","16016","enGB"

Thank you

I also don't undestand why length of unknown #A != length of unknown #B
