Introduction ------------ libgourou is a free implementation of Adobe's ADEPT protocol used to add DRM on ePub/PDF files. It overcomes the lack of Adobe support for Linux platforms. Architecture ------------ Like RMSDK, libgourou has a client/server scheme. All platform specific functions (crypto, network...) have to be implemented in a client class (that derives from DRMProcessorClient) while server implements ADEPT protocol. A reference implementation using cURL, OpenSSL and libzip is provided (in _utils_ directory). Main functions to use from gourou::DRMProcessor are: * Get an ePub from an ACSM file : _fulfill()_ and _download()_ * Create a new device : _createDRMProcessor()_ * Register a new device : _signIn()_ and _activateDevice()_ * Remove DRM : _removeDRM()_ * Return loaned book : _returnLoan()_ You can import configuration from (at least): * Kobo device : .adept/device.xml, .adept/devicesalt and .adept/activation.xml * Bookeen device : .adobe-digital-editions/device.xml, root/devkey.bin and .adobe-digital-editions/activation.xml Or create a new one. Be careful: there is a limited number of devices that can be created by one account. ePub are encrypted using a shared key: one account / multiple devices, so you can create and register a device into your computer and read downloaded (and encrypted) ePub file with your eReader configured using the same AdobeID account. For those who want to remove DRM without adept_remove, you can export your private key and import it within [Calibre](https://calibre-ebook.com/) an its DeDRM plugin. Dependencies ------------ For libgourou: _externals_ : * libpugixml _internals_: * uPDFParser For utils: * libcurl * OpenSSL * libzip * libpugixml Internal libraries are automatically fetched and statically compiled during the first run. When you update libgourou's repository, **don't forget to update internal libraries** with: make update_lib Compilation ----------- Use _make_ command make [CROSS=XXX] [DEBUG=(0*|1)] [STATIC_UTILS=(0*|1)] [BUILD_UTILS=(0|1*)] [BUILD_STATIC=(0*|1)] [BUILD_SHARED=(0|1*)] [all*|clean|ultraclean|build_utils|install|uninstall] CROSS can define a cross compiler prefix (ie arm-linux-gnueabihf-) DEBUG can be set to compile in DEBUG mode BUILD_UTILS to build utils or not STATIC_UTILS to build utils with static library (libgourou.a) instead of default dynamic one (libgourou.so) BUILD_STATIC build libgourou.a if 1, nothing if 0, can be combined with BUILD_SHARED BUILD_SHARED build libgourou.so if 1, nothing if 0, can be combined with BUILD_STATIC other variables are DESTDIR and PREFIX to handle destination install directory * Default value Utils ----- First, add libgourou.so to your LD_LIBRARY_PATH export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD You can optionaly specify your .adept directory export ADEPT_DIR=/home/XXX Then, use utils as following: You can import configuration from your eReader or create a new one with _utils/adept\_activate_: ./utils/adept_activate -u Then a _/home//.config/adept_ directory is created with all configuration file To download an ePub/PDF: ./utils/acsmdownloader To export your private key (for DeDRM software): ./utils/acsmdownloader --export-private-key [-o adobekey_1.der] To remove ADEPT DRM: ./utils/adept_remove To list loaned books: ./utils/adept_loan_mgt [-l] To return a loaned book: ./utils/adept_loan_mgt -r You can get utils full options description with -h or --help switch Docker ------ A docker image (by bcliang) is available at [https://github.com/bcliang/docker-libgourou/](https://github.com/bcliang/docker-libgourou/) Copyright --------- Grégory Soutadé License ------- libgourou : LGPL v3 or later utils : BSD Special thanks -------------- * _Jens_ for all test samples and utils testing * _Milian_ for debug & code * _Berwyn H_ for all test samples, feedbacks, patches and kind donation Donation -------- https://www.paypal.com/donate/?hosted_button_id=JD3U6XMZCPHKN Donators -------- * _Berwyn H_ * _bwitt_
