Sorry, I'm somewhat lost. Why should someone know such a strange thing?
Reversing is all around us -- Samba for MS protocols, OpenOffice for MS
formats, The Unarchiver for unrar etc. Or to get closer to john -- many
hash formats were not documented and were reversed by interested people.
You are in security and still think that reversing is wrong? Or that
distributing results of reversing is wrong? Or using freely available
unrar for reversing is wrong?
