Perform the following conversions with one command:
|
Convert ACSM files to PDF/EPUBs with one command on Linux ([and MacOS very soon](https://github.com/BentonEdmondson/knock/issues/58)).
|
||||||
* ACSM → EPUB
|
|
||||||
* ACSM → PDF
|
|
||||||
* (Soon: AAX → M4B)
|

|
||||||
|
|
||||||
## Setup and Installation
|
## Installation
|
||||||
|
|
||||||
* For NixOS users, include this flake in your system `flake.nix`. Then run `knock ~/path/to/my-book.acsm` to use.
|
* Download the latest [release](https://github.com/BentonEdmondson/knock/releases). Make sure it is the correct version for your architecture (run `uname -m` to check).
|
||||||
```nix
|
* Rename the binary and make it executable.
|
||||||
{
|
* Run `knock /path/to/book.acsm` to perform the conversion.
|
||||||
inputs.knock.url = "github:BentonEdmondson/knock";
|
|
||||||
outputs = { self, knock }: { /* knock.defaultPackage.x86_64-linux is the package */ };
|
|
||||||
}
|
|
||||||
```
|
|
||||||
* For non-NixOS, use the latest [release](https://github.com/BentonEdmondson/knock/releases). It is large because it includes all dependencies, allowing it to run on any system with an x86_64 Linux kernel. It was built using [`nix bundle`](https://nixos.org/manual/nix/unstable/command-ref/new-cli/nix3-bundle.html). Use it by doing the following:
|
|
||||||
1. Download `knock-version-x86_64-linux` and open a terminal
|
|
||||||
1. Navigate to the folder within which `knock-version-x86_64-linux` resides (e.g. `cd ~/Downloads`)
|
|
||||||
1. Run `mv knock-version-x86_64-linux knock` to rename it to `knock`
|
|
||||||
1. Run `chmod +x knock` to make it executable
|
|
||||||
1. Run `./knock ~/path/to/my-book.acsm` to convert the ebook
|
|
||||||
|
|
||||||
If you receive an error that says something like `./nix/store/...: not found` or `./nix/store/...: No such file or directory` then you might not have user namespaces enabled. Try running the following to fix it:
|
|
||||||
|
|
||||||
```
|
|
||||||
echo "kernel.unprivileged_userns_clone=1" >> /etc/sysctl.conf
|
|
||||||
sudo reboot
|
|
||||||
```
|
|
||||||
If you receive an error that says something like `E_AUTH_FAILED http://adeactivate.adobe.com/adept/SignInDirect xxxx@xxxxxxxx.com CUS05051` then you might have over (at least) 10 digit password for Adobe. Try changing it to 10 digit password and try the command again.
|
|
||||||
|
|
||||||
1. Optionally move the executable to `~/bin` (for your user) or `/usr/local/bin/` (for all users) to allow it to run from anywhere (might not work on some distributions)
|
|
||||||
|
|
||||||
## Recommended Workflows
|
|
||||||
|
|
||||||
Before buying your ebook/audiobook, check if it is available for free on [Project Gutenberg](https://gutenberg.org/) (ebooks) or [LibriVox](https://librivox.org/) (audiobooks).
|
|
||||||
|
|
||||||
If you're looking for an ebook reader or audiobook player, I recommend [Foliate](https://johnfactotum.github.io/foliate/) for the former and [Cozy](https://cozy.sh/) for the latter.

## Dependencies
|
## Dependencies
|
||||||
|
|
||||||
* [`libgourou`](http://indefero.soutade.fr/p/libgourou/) for using the ACSM file to download the corresponding encrypted EPUB/PDF file from Adobe's servers
|
There are no userspace runtime dependencies.
|
||||||
* [`rmdrm`](https://github.com/BentonEdmondson/rmdrm/) for decrypting the Adobe ADEPT-encrypted EPUB/PDF files
|
|
||||||
* [`Audible`](https://github.com/mkb79/Audible) for fetching the Audible decryption key used to decrypt AAX files
|
|
||||||
* [`ffmpeg`](https://www.ffmpeg.org/) for converting AAX files to M4B files using the Audible decryption key
|
|
||||||
|
|
||||||
These are already included in all releases and in the Nix flake of course.
|
## Building & Contributing
|
||||||
|
|
||||||
