Amazon Kindle Hack: Read DRM-protected Mobipocket content
![]() No question, this development will delight all Kindle customers but perhaps provide no small amount of frustration to the good folks over at Amazon. You can download the tools (written in Python) over here: link removed on Amazon's request |

Igor does this mean you've abandoned your Sony Reader projects?

The question is if Amazon will do a Apple and update the kindle with some kind of protection against this?

I don't have a Kindle yet, but I downloaded it anyway, just in case he gets a cease and desist from Amazon.

Hmph, if the PID is generated from the serial number, I don't see a way for them to "fix" this, without also breaking access to our "legit" Kindle purchases. It's interesting. I wonder if he can do the reverse, de-Kindle an AZW file I've purchased from Amazon. That would allow me to read all my content on my Gen3!

Wouldn't this be an excellent case for "Fair Use"? No DRM is cracked, no protection is broken, no copyrights violated.
A "deKindleizer" would be a great idea! All those cheap Kindle books from Amazon, usable on other readers like the iLiad or the Cybook... *yum* |

You'd still have to get the PID for those other devices into the files, though, wouldn't you?

Hadn't considered that. In that case, I guess it's probably not such a good idea. Most mobi sites allow you to have more than one device, but Amazon only allows Kindle content to be read on the Kindle (or multiple Kindles, from what I can discern).

Agreed. And this (getting the PID into AZW files) could be considered breaking of the DRM, which is probably really not a good idea.

This device should do this out of the box. There is no reason why my books purchased in Amazon's Mobipocket DRM should not work with Amazon's ebook reader.
I'm sick of DRM. I only wish there was an easy way to strip the DRM from these so I can read the stuff I buy on the device I choose. Makes you want to go back to paper books. |

There is still a chance for this to be broken. Since Amazon owns Mobipocket, if they can identify the PIDs used by Kindles, they could disallow those at the authenticating server; thus no new books could be encrypted with those PIDs.
Just a thought. Make sure you keep backup copies of those Mobipocket books. *back to reading my iLiad* |

Thanks to igorsk who released the code we know that a crc32 routine is involved in calculating the PIDs for Kindle devices. Since it's relatively easy to reverse crc32, I assume xianfox is right - Amazon could theoratically determine if the PID is related to a specific Kindle serial.
