Cryptimage is an open source software under the license GNU GPL v3 which purpose is to reproduce old analog TV encryption systems.
Systems simulated are :
-
discret 11 (used between 1984 and 1995 by french TV network "canal plus")
-
nagravision syster (used between 1995 and 2010)
-
videocrypt (used by Sky TV and by several other broadcasters on astra satellites)
-
MAC-Eurocrypt
This software allows to encrypt a video file (image and sound) , and allows also a decryption of an encrypted file, by meeting the standard discret11, nagravision syster, videocrypt and MAC-Eurocrypt. Besides the ability to reproduce in a digital way these encryption systems, its second use is to allow the re-use of hardware descramblers by injecting to them an encrypted video file produced by cryptimage.
