from the doc: 'only 0x0001 -- What f*ck ....? Hi, my little dude!!!! Do u wanna know what f k is that??? U can use ShadowJPEG simply for hide your private files into normal jpeg images. To compile ShadowJPEG type: ./make 0x0010 -- Current Release 1.0 -- Added an encript/decript function using a private key what has a variable lenght. 0.2b -- Fixed a f king seg-fault. 0.1a -- The first release 0x0011 -- Bugs O o I dunno why... but the injection doesn't seem to work fine on Windows(sux)... It creates a jpeg file... and it's ok... but if u try to open it with paint it gives u "unknow file format"... i'm so sorry for this bug... Otherwise it works fine on linux ;-) '
