Bump dependency requirements to their current latest and migrate the code for the breaking API changes; refresh Cargo.lock for the rest. Notable version bumps: * zip 2 -> 8, quick-xml 0.37 -> 0.40, toml 0.8 -> 1 * windows 0.58 -> 0.62, winreg 0.52 -> 0.56 * RustCrypto: aes 0.8 -> 0.9, cbc 0.1 -> 0.2, sha1/sha2 0.10 -> 0.11, md-5 0.10 -> 0.11, ctr 0.9 -> 0.10, hmac 0.12 -> 0.13, pbkdf2 0.12 -> 0.13 Code migrations: * quick-xml 0.40: BytesText::unescape() -> xml10_content(); Attribute::unescape_value() -> normalized_value(XmlVersion::Implicit1_0) * windows 0.62: LocalFree now takes Option<HLOCAL> * cipher 0.5 (aes 0.9 / cbc 0.2): BlockEncryptMut/BlockDecryptMut -> BlockModeEncrypt/BlockModeDecrypt; encrypt_padded_mut/decrypt_padded_mut -> encrypt_padded/decrypt_padded Held back deliberately: rand stays 0.8 because the latest rsa (0.9) still needs an rand_core 0.6 RNG for keygen, which rand 0.9+ no longer provides. rsa pinning the older RustCrypto generation also leaves a couple of duplicate transitive versions (digest 0.10/0.11, crypto-common 0.1/0.2) — harmless. Verified: 46 tests pass, clippy + rustfmt clean, and a real ADEPT EPUB still decrypts end-to-end (DPAPI key extraction + RSA/AES) to a valid DRM-free file.

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
