LCP Removal Script

Requirements

Before running the script, ensure you have the necessary dependencies installed. You can do so by running:

pip install pycryptodome

Open the .lcpl file in Thorium Reader:
Thorium is a free ebook reader that supports LCP-protected files. You can download it from the official website.
Export the ebook as an .lcpa file:
- In Thorium Reader, right-click on the book you want to decrypt.
- Select the option to export it as an .lcpa file (LCP archive).
Run the decryption script:
Use the following command to decrypt the .lcpa file:
```
python lcpremove.py -key <your_passphrase_key> <path_to_ebook_file>
```
Replace <your_passphrase_key> with the passphrase you received when purchasing or borrowing the ebook, and <path_to_ebook_file> with the path to the .lcpa file.
Access the decrypted files:
Once the script runs successfully, all decrypted content will be saved in a new folder created in the same directory as the .lcpa file.
- If the .lcpa file contains an image file (such as .jpg, .jpeg, or .png) for an audiobook, the image will automatically be copied to the output folder.

This script has been tested on both Windows and Linux.
Although Thorium is used here as an example for exporting LCP-protected audiobooks and ebooks, any LCP-compatible software with export functionality can be used.
