Introduction
------------
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.
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()_
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.
Dependencies
------------
For libgourou :
* None
For utils :
* QT5Core
* QT5Network
* OpenSSL
* libzip
Compilation
-----------
Use _make_ command
make [CROSS=XXX] [DEBUG=1]
CROSS can define a cross compiler prefix (ie arm-linux-gnueabihf-)
DEBUG can be set to compile in DEBUG mode
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 <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>
