A patch to fix LCP DRM removal in NoDrm’s Dedrm or its forks
Description
This is a simple patch that should, in theory, return ability to remove LCP DRM that was crippled by the fraudulent DMCA request in original repo by litigious scum that invests in lawyers and bribes instead of technical competence. 2.0-2.9 profiles should work.
Usage
The tool supports .epub, .pdf, and .lcpl (beta) files. It can be run either via a standalone Windows executable or a Docker container.
If the passphrase is not provided via the command line, the program will attempt to read it from a passphrase.txt file (one passphrase per line). If this file is missing, it will be created automatically, and the program will exit so you can populate it.
The decrypted output file will be saved in the same directory as the source file, appended with the _DECRYPTED suffix.
Windows
- Download the prebuilt executable from GitFlic Releases.
- Open PowerShell or CMD and run:
# With a specific passphrase
.\lcpdedrm.exe "C:\path\input.epub" "YOUR_PASSPHRASE"
# Using the auto-generated passphrase.txt file
.\lcpdedrm.exe "C:\path\input.epub"
(Note: passphrase.txt is read from or created in the same folder as the .exe file).
Docker
You can run the tool directly using the GitFlic Docker image. Mount your current directory to /data so the container can access your files.
# With a specific passphrase
docker run --rm -v "${PWD}:/data" registry.gitflic.ru/project/mikudaio/dedrmlcpatch/lcpdedrm:latest "/data/input.epub" "YOUR_PASSPHRASE"
# Using the auto-generated passphrase.txt file
docker run --rm -v "${PWD}:/data" registry.gitflic.ru/project/mikudaio/dedrmlcpatch/lcpdedrm:latest "/data/input.epub"
Notes
- Lcpdf support is not tested. Fix it yourself if there are problems
- Profiles 2.1-2.9 are partially tested, but who knows?
- No support is provided for this repo
- Seriously, no support. Figure problems out yourself
- LCPL files would cause Calibre to (try to) download book from the web. There are no checks on download, and it might cause side effects. or not. On your own head be it.
