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

Windows

Download the prebuilt executable from releases:

GitFlic Releases

Then run from PowerShell or CMD:

.\lcpdedrm.exe "C:\path\input.epub" "YOUR_PASSPHRASE"

You can also use .pdf input, or .lcpl input:

.\lcpdedrm.exe "C:\path\input.lcpl" "YOUR_PASSPHRASE"

Output is written next to the source file with _DECRYPTED suffix.

Docker

Run directly from GitFlic image:

docker run --rm -v "${PWD}:/data" registry.gitflic.ru/project/mikudaio/dedrmlcpatch/lcpdedrm:latest "/data/input.epub" "YOUR_PASSPHRASE"

Arguments:

• input.epub (or .pdf): encrypted input file in mounted folder.
• YOUR_PASSPHRASE: LCP passphrase.
• output_name: output base path/name (without extension), written in mounted folder.

Support in beta even for .lcpl file

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.
