Video Padlock 1.12

Video Padlock is easy to use encryption software that ensures that your downloaded videos are secure and remain private. Create a master password, choose the files you want to encypt and click a button. The files disappear from view and are only viewable and playable from within Video Padlock after you enter your password. Playback of large files is instant thanks to a unique partial encryption feature. In partial encryption mode the first 50KB of a file are encrypted rendering the file unplayabe and unrecognizable.

Video Padlock encrypts files with ultra-secure 128 bit ARC4 encryption, the standard process used by governments and industries around the world.
Video Padlock can also be used to protect audio or any other file type with this robust security.
Try the demo - it is fully functional you are just limited to having two videos encrypted at one time.
