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 :

  • None

For utils :

  • QT5Core
  • QT5Network
  • OpenSSL
  • libzip


User make

_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


You can import configuration from your eReader or create a new one with utils/activate :

./utils/activate -u <USERNAME>

Then a ./.adept directory is created with all configuration file

To download an ePub :

./utils/acsmdownloader -f <ACSM_FILE>
