Interesting work around for Amazon’s new Kindle eBook reader, Igor writes –
We’ve known for some time already that Amazon’s AZW files are actually Mobi files, but Amazon didn’t share Kindle’s Mobi PID which would allow one to buy encrypted Mobi books for Kindle. Well, I’ve discovered the algorithm used to generate the PID and was able to use it on Fictionwise, but there was another catch. AZW files have a flag set in the DRM info which is not present in books bought from other vendors. After fixing that, I could read the book on Kindle. Linked archive includes two Python scripts.
