| 3 | ␊ |
| 4 | 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.␊ |
| 5 | ␊ |
| 6 | ␊ |
| 7 | Architecture␊ |
| 8 | ------------␊ |
| 9 | ␊ |
| 10 | 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.␊ |
| 11 | A reference implementation using Qt, OpenSSL and libzip is provided (in _utils_ directory).␊ |
| 12 | ␊ |
| 13 | Main fucntions to use from gourou::DRMProcessor are :␊ |
| 14 | ␊ |
| 15 | * Get an ePub from an ACSM file : _fulfill()_ and _download()_␊ |
| 16 | * Create a new device : _createDRMProcessor()_␊ |
| 17 | * Register a new device : _signIn()_ and _activateDevice()_␊ |
| 18 | * Remove DRM : _removeDRM()_␊ |
| 19 | * Return loaned book : _returnLoan()_␊ |
| 20 | ␊ |
| 21 | You can import configuration from (at least) :␊ |
| 22 | ␊ |
| 23 | * Kobo device : .adept/device.xml, .adept/devicesalt and .adept/activation.xml␊ |
| 24 | * Bookeen device : .adobe-digital-editions/device.xml, root/devkey.bin and .adobe-digital-editions/activation.xml␊ |
| 25 | ␊ |
| 26 | Or create a new one. Be careful : there is a limited number of devices that can be created bye one account.␊ |
| 27 | ␊ |
| 28 | 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.␊ |
| 29 | ␊ |
| 30 | 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.␊ |
| 31 | ␊ |
| 32 | ␊ |
| 33 | Dependencies␊ |
| 34 | ------------␊ |
| 35 | ␊ |
| 36 | For libgourou :␊ |
| 37 | ␊ |
| 38 | _externals_ :␊ |
| 39 | ␊ |
| 40 | * libpugixml␊ |
| 41 | ␊ |
| 42 | _internals_ :␊ |
| 43 | ␊ |
| 44 | * uPDFParser␊ |
| 45 | ␊ |
| 46 | For utils :␊ |
| 47 | ␊ |
| 48 | * libcurl␊ |
| 49 | * OpenSSL␊ |
| 50 | * libzip␊ |
| 51 | * libpugixml␊ |
| 52 | ␊ |
| 53 | ␊ |
| 54 | Internal libraries are automatically fetched and statically compiled during the first run.␊ |
| 55 | When you update libgourou's repository, **don't forget to update internal libraries** with :␊ |
| 56 | ␊ |
| 57 | make update_lib␊ |
| 58 | ␊ |
| 59 | ␊ |
| 60 | Compilation␊ |
| 61 | -----------␊ |
| 62 | ␊ |
| 63 | Use _make_ command␊ |
| 64 | ␊ |
| 65 | 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|install|uninstall]␊ |
| 66 | ␊ |
| 67 | CROSS can define a cross compiler prefix (ie arm-linux-gnueabihf-)␊ |
| 68 | ␊ |
| 69 | DEBUG can be set to compile in DEBUG mode␊ |
| 70 | ␊ |
| 71 | BUILD_UTILS to build utils or not␊ |
| 72 | ␊ |
| 73 | STATIC_UTILS to build utils with static library (libgourou.a) instead of default dynamic one (libgourou.so)␊ |
| 74 | ␊ |
| 75 | BUILD_STATIC build libgourou.a if 1, nothing if 0, can be combined with BUILD_SHARED␊ |
| 76 | ␊ |
| 77 | BUILD_SHARED build libgourou.so if 1, nothing if 0, can be combined with BUILD_STATIC␊ |
| 78 | ␊ |
| 79 | * Default value␊ |
| 80 | ␊ |
| 81 | ␊ |
| 82 | Utils␊ |
| 83 | -----␊ |
| 84 | ␊ |
| 85 | First, add libgourou.so to your LD_LIBRARY_PATH␊ |
| 86 | ␊ |
| 87 | export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD␊ |
| 88 | ␊ |
| 89 | You can optionaly specify your .adept directory␊ |
| 90 | ␊ |
| 91 | export ADEPT_DIR=/home/XXX␊ |
| 92 | ␊ |
| 93 | Then, use utils as following :␊ |
| 94 | ␊ |
| 95 | You can import configuration from your eReader or create a new one with _utils/adept\_activate_ :␊ |
| 96 | ␊ |
| 97 | ./utils/adept_activate -u <AdobeID USERNAME>␊ |
| 98 | ␊ |
| 99 | Then a _/home/<user>/.config/adept_ directory is created with all configuration file␊ |
| 100 | ␊ |
| 101 | To download an ePub/PDF :␊ |
| 102 | ␊ |
| 103 | ./utils/acsmdownloader <ACSM_FILE>␊ |
| 104 | ␊ |
| 105 | To export your private key (for DeDRM software) :␊ |
| 106 | ␊ |
| 107 | ./utils/acsmdownloader --export-private-key [-o adobekey_1.der]␊ |
| 108 | ␊ |
| 109 | To remove ADEPT DRM :␊ |
| 110 | ␊ |
| 111 | ./utils/adept_remove <encryptedFile>␊ |
| 112 | ␊ |
| 113 | To list loaned books :␊ |
| 114 | ␊ |
| 115 | ./utils/adept_loan_mgt [-l]␊ |
| 116 | ␊ |
| 117 | To return a loaned book :␊ |
| 118 | ␊ |
| 119 | ./utils/adept_loan_mgt -r <id>␊ |
| 120 | ␊ |
| 121 | ␊ |
| 122 | You can get utils full options description with -h or --help switch␊ |
| 123 | ␊ |
