DRMLibre is a standalone, single-binary Rust CLI that removes DRM from
Amazon Kindle and Adobe Digital Editions ebooks. The decryption logic is
ported from DeDRM_tools (GPLv3); this project is GPL-3.0-or-later.
This commit covers the first three milestones of the plan:
* Phase 0 - workspace scaffold (drmlibre-core engine + drmlibre-cli),
native TOML config, magic-byte/zip-content format detection, and the
remove/passhash/config CLI surface with atomic output handling.
* Phase 1 - Adobe ADEPT EPUB: RSA (PKCS#1 v1.5) and PassHash book-key
unwrap, RMSDK>=10 hardening, AES-128-CBC content decryption, and IETF/
Adobe font de-obfuscation. Verified end-to-end with a real RSA key.
* Phase 2 - Kindle MOBI/AZW/AZW3: PC1 cipher, type-1 and type-2 DRM,
serial->PID derivation, EXTH header patches, and trailing-data handling.
Verified end-to-end and against the upstream golden vectors.
All crypto is pure Rust (RustCrypto), so the release binary has no
third-party runtime dependencies. 42 tests pass; clippy and rustfmt clean.
