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/adept\_activate_ :
|
|
|
|
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
|
|
./utils/adept_activate -u <AdobeID USERNAME>
|
|
|
|
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 <ACSM_FILE>
|
|
|
|
To export your private key (for DeDRM software) :
|
|
|
|
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 <encryptedFile>
|
|
|
|
You can get utils full options description with -h or --help switch
