libgourou is a free implementation of Adobe's ADEPT protocol used to add DRM on ePub files. It overcome the lacks of Adobe support for Linux platforms.
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()
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 libgourou :
For utils :
Use make command
make [CROSS=XXX] [DEBUG=1] [STATIC_UTILS=1]
CROSS can define a cross compiler prefix (ie arm-linux-gnueabihf-)
DEBUG can be set to compile in DEBUG mode
STATIC_UTILS to build utils with static library (libgourou.a) instead of default dynamic one (libgourou.so)
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 <AdobeID USERNAME>
Then a ./.adept directory is created with all configuration file
To download an ePub :
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD ./utils/acsmdownloader -f <ACSM_FILE>
libgourou : LGPL v3 or later
utils : BSD
