The requirements for the Vernam cipher are very simple: - the pad must be random - the pad must not be reused - the pad must be secret (it's the key!) These formats (e.g. mp3) have headers, etc. http://mpgedit.org/mpgedit/mpeg_format/mpeghdr.htm Anyway, the data is not random, so it should not be used as a one-time-pad. Regards. q
