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()_
* Return loaned book : _returnLoan()_

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 :

_externals_ :

* None

_internals_ :

* PugiXML
* uPDFParser

For utils :

* libcurl
* OpenSSL
* libzip

Internal libraries are automatically fetched and statically compiled during the first run.
When you update libgourou's repository, **don't forget to update internal libraries** with :

make update_lib

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*)] [all*|clean|ultraclean|build_utils]

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

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 (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

To list loaned books :

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
./utils/adept_loan_mgt [-l]

To return a loaned book :

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
./utils/adept_loan_mgt -r

You can get utils full options description with -h or --help switch
