docker-libgourou

Dockerized version of libgourou. libgourou is a free implementation of Adobe's ADEPT protocol. ADEPT is used to manage loaned ePub/PDF titles (checkout/return). It is also used to manage DRM in loaned ePub/PDF files.

libgourou

libgourou requires an Adobe ID but runs on Linux platforms (no WINE-based workaround required).

utils

This container compiles the reference implementation utilities for libgourou (master branch) and places them in /usr/local/bin for easy access.

  • acsmdownloader for downloading ePub/PDF files from Adobe's CDN
  • adept_activate for activating user device via Adobe ID
  • adept_loan_mgt for managing ADEPT loan library
  • adept_remove for removing ADEPT DRM from an ADEPT-protected ePub/PDF

Installation

Local Build

> docker build . -f Dockerfile-ubuntu -t bcliang/docker-libgourou

or on alpine:

> docker build . -f Dockerfile-alpine -t bcliang/docker-libgourou

DockerHub

> docker pull bcliang/docker-libgourou:latest

The :latest tag will pull the :ubuntu image. Use :ubuntu or :alpine to specify the desired base image (warning: segmentation faults when running the alpine build in 0.8.4).

Usage

Automated download and de-drm

By default, the container will process an inputted *.acsm file ($1) through both acsmdownloader (to retreive the PDF/ePub file) and adept_remove (to remove ADEPT DRM from the downloaded file).

> docker run \
    -v {$PATH_TO_ADOBE_CREDS}:/home/libgourou/.adept \
    -v $(pwd):/home/libgourou/files \
    --rm bcliang/docker-libgourou \
    [name_of_adept_metafile.acsm]

Notes:

  1. The shell script assumes that activated device configuration files (via Adobe ID credentials) have been mounted into /home/libgourou (alternates: /home/libgourou/.adept/, /home/libgourou/adobe-digital-editions/, etc.).
  2. To generate ADEPT configuration files (activation.xml, devicesalt, device.xml), use the interactive terminal and run the adept_activate utility.

Interactive Terminal

To manually run libgourou utils, run the container interactively and overide the docker entrypoint:

> docker run \
    -v {$PATH_TO_ADOBE_CREDS}:/home/libgourou/.adept \
    -v $(pwd):/home/libgourou/files \
    -it --entrypoint /bin/bash \
    bcliang/docker-libgourou

Commands

Use the bash shell to run the libgourou utility scripts. See the libgourou README and/or the included manpages for additional usage.

To activate a new device with a AdobeID :

adept_activate -u <AdobeID USERNAME> [--output-dir output_directory]

By default, configuration files will be saved in /home/libgourou/.adept. Users should save contents to a mounted volume for reuse at a later date.

To download an ePub/PDF :

acsmdownloader <ACSM_FILE>

To export your private key (for use with Calibre, for example) :

acsmdownloader --export-private-key [-o adobekey_1.der]

To remove ADEPT DRM :

adept_remove <encrypted_file>

To list loaned books :

adept_loan_mgt [-l]

To return a loaned book :

adept_loan_mgt -r <id>

Bash Script

A "de-DRM" bash script is provided (./scripts/dedrm.sh) to simplify running and using the docker-libgourou image.

> chmod +x scripts/dedrm.sh
> cp scripts/dedrm.sh ~/.local/bin/dedrm

To launch an interactive terminal with access to the libgourou utils:

> dedrm
!!!    WARNING: no ADEPT keys detected (argument $2, or "$HOME_DIR/.config/adept").
!!!    Launching interactive terminal for credentials creation (device activation). Run this:

 > adept_activate --random-serial \
       --username {USERNAME} \
       --password {PASSWORD} \
       --output-dir files/adept

!!!     (*) use --anonymous in place of --username, --password if you do not have an ADE account.
!!!     (*) credentials will be saved in the following path: "$(pwd)/adept"

!!!    WARNING: no ACSM file detected (argument $1).
!!!    Launching interactive terminal for manual loan management. Example commands below:

 > acsmdownloader \
       --adept-directory .adept \
       --output-file encrypted_file.drm \
       "files/{ACSM_FILE}"
 > adept_remove \
       --adept-directory .adept \
       --output-dir files \
       --output-file "{OUTPUT_FILE}" \
       encrypted_file.drm

Mounted Volumes
   (current path e.g. $pwd) --> /home/libgourou/files/

root@..:/home/libgourou# 

If you already have ADEPT keys saved (i.e. in .adept or ~/.config/adept), append the encrypted ACSM file path in order to automatically generate a DRM-removed PDF/ePub file (this simply replicates the command at the top of this section):

> dedrm {ACSM_FILE}

To generate a DRM-free PDF/ePub file using credentials in a specific path:

> dedrm {ACSM_FILE} {CREDENTIALS_PATH}
