Is the End-To-End Encryption (E2EE) of Joplin (notes app) secure enough for public Git repo?

Because recommends Joplin I am switching my notes to it. I add the text files to Git, and wonder if I can also use a public Repo and/or a cloud hosted Git server?

I will paste sensitive info like API tokens and passwords into the notes.

I enabled About End-To-End Encryption (E2EE)🔗 / docs with very strong pass (in local KeePassXC) and file synchronisation to a Git repo.

Encrypted data is encoded to ASCII because encryption/decryption functions in React Native can only deal with strings. So for compatibility with all the apps we need to use the lowest common denominator.

Too complicated for me.
