Introduction ------------ libgourou is a free implementation of Adobe's ADEPT protocol used to add DRM on ePub/PDF files. It overcome the lacks of Adobe support for Linux platforms. Architecture ------------ Like RMSDK, libgourou has a client/server scheme. All platform specific functions (crypto, network...) has to be implemented in a client class (that derives from DRMProcessorClient) while server implements ADEPT protocol. A reference implementation using Qt, OpenSSL and libzip is provided (in _utils_ directory). Main fucntions 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()_ 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 bye 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 wants 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 : * None For utils : * QT5Core * QT5Network * OpenSSL * libzip 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*)] 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 * Default value Utils ----- You can import configuration from your eReader or create a new one with utils/activate : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD ./utils/activate -u Then a _./.adept_ directory is created with all configuration file To download an ePub/PDF : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD ./utils/acsmdownloader -f To export your private key : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD ./utils/acsmdownloader --export-private-key [-o adobekey_1.der] To remove ADEPT DRM : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD ./utils/adept_remove -f Copyright --------- Grégory Soutadé License ------- libgourou : LGPL v3 or later utils : BSD Special thanks -------------- * _Jens_ for all test samples and utils testing
