Introduction

libgourou is a free implementation of Adobe's ADEPT protocol used to add DRM on ePub/PDF files. It overcomes the lack of Adobe support for Linux platforms.
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...) have to be implemented in a client class (that derives from DRMProcessorClient) while server implements ADEPT protocol.
A reference implementation using cURL, OpenSSL and libzip is provided (in _utils_ directory).

A reference implementation using Qt, OpenSSL and libzip is provided (in _utils_ directory).
Main functions to use from gourou::DRMProcessor are:
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 by one account.
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 want 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.

For libgourou :
_externals_ :
* libpugixml
_internals_:
* uPDFParser
* None
For utils :
* libcurl
* openssl
* OpenSSL
* libzip
* libpugixml
External & utils dependencies has to be installed by your package manager (_apt_ for example).
Use _-dev_ flavours to get needed headers.
Internal libraries are automatically fetched and statically compiled during the first compilation.
When you update libgourou's repository, **don't forget to update internal libraries** with:
make update_lib

Utils
-----
First, add libgourou.so to your LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
You can optionaly specify your .adept directory
export ADEPT_DIR=/home/XXX
Then, use utils as following:
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 _/home/<user>/.config/adept_ directory is created with all configuration file
Then a _./.adept_ directory is created with all configuration file
To download an ePub/PDF :
./utils/acsmdownloader <ACSM_FILE>
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 :
./utils/adept_remove <encryptedFile>
To list loaned books:
./utils/adept_loan_mgt [-l]
To return a loaned book:
./utils/adept_loan_mgt -r <id>
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
