FAQ:How do I know the machine ID of the user''s computer? When a user wants to open an encrypted file the encrypted file will pop up a dialog box to request the user to enter a Playback Password. This dialog box will display the machine ID of the user''s computer. The user can send his/her own machine ID to you and you can create a Playback Password based on the user''s machine ID. After that the user can use this Read Password to open your file on his/her computer. Since the Playback Password is created based on the user''s machine ID the user will not be able to share the Playback Password with other users the user will not be able to re-distribute your files PPT2EXEpps2exepptx2exeppsx2exe If this is your first time to use this encryption tool please watch the video demonstration on how to encrypt ppt.You can find the video demo in the downloaded package.
