Definitely need help advancing. I’m after login screen for about a week now 
Got all the .php files, enumerated sqlite, no idea how to proceed.
Will appreciate any help.
Thank you
Edit:
Thanks to @Pilot51 for the help with getting the foot down.
This part was crazy hard for me and not because of encryption.
I literally tried tens different ways to get inside after I already had all the information collected
After you’re inside the encryption theme continues and gets more interesting
It took me couple of weeks to get initial foothold (and I don’t mean the login screen)
and then the user and root part were much clearer
Thanks to the box creators @no0n3 and @Adamm it was real challenge and pleasure (though I have more gray hairs now 
)
