MSIX Kindle Key Finder

A Windows utility that extracts DRM keys from the Amazon Kindle Store App (MSIX/UWP) and optionally imports your Kindle books into Calibre with DeDRM applied.

What It Does

The Kindle app from the Microsoft Store uses the MSIX packaging format. Unlike the classic Kindle desktop app, this version stores DRM keys in a way that requires a specialized extraction process. This tool automates that entire process:

• Detects your installed Kindle Store app version
• Locates your downloaded Kindle book content
• Uses the MSIXKFXArchiver tool to extract DRM keys (DSN / Tokens)
• Optionally imports your books into Calibre with the DeDRM plugin

Version Checking

The script automatically checks GitHub for the latest release on startup and notifies you if an update is available.

Notes

• Running from a OneDrive / cloud-synced folder may cause permission issues. It is recommended to run from a local directory.
• The script warns if Calibre is running before attempting import phases to prevent database corruption.
• DRM keys are partially obfuscated in on-screen output by default to protect sensitive data.
