Everything is crackable...
Like I have said for years now. If it is human made, a human can crack it. It is just a matter of time.
Obviously the amount of time depends on the level of interest.
R.I.P. CSS - 1999
R.I.P. WEP - 2001
R.I.P. AACS - 2007
R.I.P. BD+ - 2008
AACS and BD+ cracked for sure? Who knows but there are lots of programs out there to let you get around it. That is close enough in my book.
