Hi Mike

Yes I am very well aware of the low security levels offered by Acrobat and Office style files. Many cracking tools available for all file formats. However, I am interested in creating a barrier that a malicous person cannot claim to have been unaware off whilst at the same time removing it. The removal of the "protection" requires a deliberate act.
