Replace specific ASINs, the book title, and the license voucher GUID with generic placeholders ahead of making the repo public. No technical content changes (the format census, vault structure, and analysis are unaffected). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
DRMLibre
A standalone, single-binary command-line tool (written in Rust, no runtime dependencies) for removing DRM from Amazon Kindle and Adobe Digital Editions ebooks. The decryption logic is ported from DeDRM_tools; DRMLibre is therefore licensed GPL-3.0-or-later. See CREDITS.md.
Use DRMLibre only on books you own, to exercise your own rights (format shifting, backup, accessibility). Respect the law in your jurisdiction.
Status
Under active development. Supported / planned formats:
| Capability | Status |
|---|---|
| Adobe ADEPT EPUB (+ hardening, B&N PassHash, font de-obfuscation) | ✅ done |
| Kindle MOBI / AZW / AZW3 | ✅ done |
| Adobe key auto-extraction from installed ADE (Windows, DPAPI) | ✅ done |
Kindle-for-PC key (.kinf) / Android / macOS auto-extraction |
planned |
| Kindle KFX-ZIP | planned |
| Adobe PDF, Kindle Topaz, eReader, Kobo, LCP | out of scope |
On Windows with Adobe Digital Editions activated, ADEPT EPUBs decrypt with no extra arguments — the key is extracted from the local install and cached in the config for later offline use.
Usage
drmlibre remove <files...> [options] # remove DRM
drmlibre passhash ... # generate/extract Adobe/B&N PassHashes
drmlibre config # summarize keys in the config file
Common remove options: -o/--output, --outputdir, -f/--force,
--overwrite, --serial, --pid, --key, --passphrase, --android-backup,
--config (default ./drmlibre.toml).
Examples:
# Adobe EPUB, using an exported Adobe key:
drmlibre remove "My Book.epub" --key adobe.der -o "My Book (no DRM).epub"
# Kindle eInk book, using the device serial:
drmlibre remove "My Book.azw" --serial 0123456789ABCDEF
Architecture
A Cargo workspace:
crates/drmlibre-core— the UI-agnostic engine (format detection, key management, decryptors). No printing or process exits; everything is aResultand progress goes throughtracing. This is what a future GUI links.crates/drmlibre-cli— thedrmlibrebinary (argument parsing, file I/O policy, exit codes).
Building
cargo build --release # binary at target/release/drmlibre
cargo test # run the test suite
