dig out deledted chat messages

Hi,

Yes, what I uploaded is a test naver_line db, we enter hidden chat mode and had chats about "MP5","AK47",and "Taipei 101"..We tried to find those messages as if it were a real case but in vain. a little frustrated …

The only clue is that Line will show the encryption keys of those two had chats in Line chat room settings, but I could not find the algorithm so far.

Recently some cases are about IM whose feature has self deconstruction like Line, Wicker…So we have to do some research and try to figure it out. We do believe some importance evidence exists in the database, and of course those chat messages are encrypted in hidden chat mode. If we could decrypt those chat messages, it will be a great help to Law Enforcement.
