1. The "Cipher" Error YouTube updates its codebase frequently to prevent scraping. If you see errors mentioning "cipher" or "extracting signature," it means pytube needs an update. Run:

pip install pytube --upgrade

If the issue persists, you may need to install the git version directly, which is often patched faster:

pip install git+https://github.com/pytube/pytube
