				Adobe ADEPT DRM for EPUB circumvented
			 
			
			I have successfully and reproducibly circumvented Adobe's ADEPT DRM system for EPUB files.  A discussion of the system and the circumvention is available in a blog post I've made on the subject: Circumventing Adobe ADEPT DRM for EPUB.

			I have no way to test this, or inclination... but glad to see it done!  Now if we could just get those damn tpz (amz1) files cracked!  And Sony's LRF.

			Good work. DRM liberation scripts are an interesting academic study. What is a .pyw file? Will this run with python 2.5? Or is 2.6 required.  BOb |

			I just looked at this more... will this not work on Mac... the comments talk about Windows. BOb |

			@BOb I believe .pyw is for Windows, where it runs the scripts using a non-console version of the inerpreter, such as for GUI apps. And it looks like the key script is for Windows only, but that you can get the key then decrypt anywhere. |

 You do need to use python 2.6, or at least the 2.6 PyCrypto needs 2.6. | |

			Any insight as to whether this will work on library books allowing them to be converted to work on a Kindle?  Or on a iPod Touch? cheers |

			Could somebody explain what an ADEPT PDF is?  And how it differs from the DRM-protected PDF files that you, say, check out from public libraries that use OverDrive/ContentReserve and the like?

			The Windows binary for PyCrypto 2.0.1 is corrupt. But, I did install Python 2.5.4 and the 2.5 version of PyCrypto and have successfully removed the DRM from a DRM infected ePub.
