Kindle for PC DRM

[LaBBa]

Hi all,
my friend just showed me this application "Kindle for PC" - http://www.amazon.com/gp/feature.html/ref=kcp_pc_mkt_lnd?docId=1000426311
that it able to read files (.prc) that are DRM and encrypted.

now i have seen in this url:
http://www.makeuseof.com/tag/how-to-strip-mobi-and-prc-ebooks-of-encryption/

that someone already found how to decrypt the DRM on a given PID of the device but for the "Kindle for PC" they didn't found yet what is the PID or where it is stored.

I'm starting to reverse the application of Amazon to see if it is possible for a user to extract his PID so he can later decrypt the book files and use it on other softwer to read other then "Kindle for PC" Amazon application.
i'm buying a sample book so i can start tracing/RE it :-)

anyone wanna join me ? (

LaBBa.
