Intresting. Allthough I didn't get a chance to RTFA, hiding encrypted data in an executable doees not seem all that practical to me. It may not change the filesize or functionality, but would it not also change other signature methods (like md5sums?). From my understanding, the main strength of steganography is the file with the encrypted data being indistinguishable from regular files. Since the diffrence can be detected with CRC or MD5, wouldn't that defeat the main purpose?
