Is there a kindle.info file on Kindles updated to 2.5.X?
Hi,
If anyone has a Kindle with firmware updated to 2.5.X or later, would you please look to see if there is a kindle.info or a .kindle_info or some file similar in name to that on the Kindle. I am wondering if software similar to KindleForPC.exe is being used on the Kindle's themselves and if so, whether information from the kindle.info file can be used to determine the book/user specific PID similar to how it is being done with the KindleForPC application now. Thanks, KevinH |

I've searched the filesystem (and I'm still searching) for anything that might be the Kindle's equivalent of the kindle.info, with no luck.
The only info used from the kindle.info file to build the book specific pid (in K4PC) is the random mazama number and the kindle account token. The rest comes from Windows user and hardware info, plus a token from the ebook itself. I remain convinced that they didn't completely reinvent the wheel on the Kindle device (or the Mac for that matter). I'm banking on a combination of: random number, hardware(serial?) info, registration info/account token and ebook token (exth 209). |

Unfortunately, I had no luck while pointing the usual Windows tools at it when I tried on the chance that it might possibly work. |

With Windows, the kindle.info file is created upon install and modified upon registration. It's encrypted (and unencrypted) using Windows' crypt32.dll library--which is responsible for basic Certificate and Cryptographic Messaging functions. I imagine the first step for a Mac solution would be finding the equivalent built-in cryptography library that is used for this same purpose.
EDIT: Which I'm guessing would have something to do with Mac's Keychain Services API. Last edited by DiapDealer; 09-09-2010 at 12:46 PM. |

I don't know what the Mac Kindle app uses as the volume serial number. HFS partitions do have one but I don't know whether it uses it. |

Speaking of random, they did add a 'guid' in the 2.5 update. (Cf. /etc/guid & /etc/init.d/guidinit). It creates a short md5sum of a bunch of random data from urandom.
No idea if it's related to the DRM scheme for the books, or for something else (KDK?). |

It could be the Keychain services API (but no new keychain entry was added when Kindle4Mac was installed - I ma not sure if that means anything at all), but it could also be the OpenSSL library which has been statically linked into the executable. I have looked but I can not figure it out. I am beginning to think an "unswindle" style approach might be the way to move forward on the Kindle4Mac side of things. Oh well, KevinH |
