I would try openpgp, you can use https://www.gpg4win.org/ on windows and https://github.com/open-keychain/open-keychain (not actively developed, if someone knows a good alternative please comment) for android.

Openkeychain is a good gnupg encryption tool for Android. https://www.openkeychain.org/. It mostly is for using gnupg for email encryption, but you can also use it for file encryption too.

Pass: The standard Unix password manager
22 projects | news.ycombinator.com | 13 Apr 2021
The Password Store app delegates key management to another app. I use OpenKeychain  for this. I believe OpenKeychain supports Yubikeys, but I haven't used that feature myself so I can't speak about how well it works.
What are some alternatives?
Android-Password-Store - Android application compatible with ZX2C4's Pass command line application
age - A simple, modern and secure encryption tool (and Go library) with small explicit keys, no config options, and UNIX-style composability.
OkcAgent - A utility that makes OpenKeychain available in your Termux shell
