The decryption key is a product of the serial number for your device, so it’s not difficult to determine. The encryption used on Kindle books is fairly basic. Choose the K4MobileDeDRM plugin’s zip file (zip within the main zip don’t extract).Download and decompress the DeDRM archive.Since the Kindle’s eBooks are encrypted, we need to install a decryption plugin to do the heavy lifting there.

Since I went through the effort of converting all of my Kindle documents, I figured I’d write a mini guide to getting it done. I could use the Kindle app for iOS but I’ve found iBooks to be faster at syncing read position, and it feels a lot more natural to use.
