Why do you even need Thorium for this?
If the files are just AES-encrypted and the links are there, as the linked article suggest, it seems that it would be easy to create a standalone script to download and decrypt these.
- edent 2y ago(OP here) I discussed how the DRM works in an earlier blog post - https://shkspr.mobi/blog/2025/03/some-thoughts-on-lcp-ebook-drm/ https://shkspr.mobi/blog/2025/03/some-thoughts-on-lcp-ebook-... Essentially, the key for decrypting the files is made up of the book owner's passphrase and the super-secret key embedded in the closed-source binary. I wasn't able to reverse engineer the binary or extract that key.
