Question

Hello. Recently Crunchyroll changed encryption for their subtitles for RPC api, so decryption will always fail.

Code fragment:

No problem on my side, maybe verbose log will be more helpful @anidl...

When getting the normal HTML frontend page, look for "subtitles":. It is followed by a JSON encoded array of subtitle entries with a language/title field and and an URL field. If you load the URL, you directly get the ASS version of the subtitle for that language. It doesn't seem to require anything special beyond extracting the URL and maybe logging in originally.
