Ask HN: What do you use GPG for?

https://www.passwordstore.org/ And signing git commits

A GPG key in Yubikey is an excellent way to manage passwords using Password Store, SSH authentication, encrypt/decrypt backups, or sensitive files in your computer so as to prevent leakage, share passwords between devices, … There are also use cases like emails data to others or yourself, but usually the other side doesn’t use email encryption!

IMO: Avoid GPG as much as you can. There are better alternatives out there. E.g. Signal, minisign, age, etc.

Secure notes with vimwiki. I version control my notes, but prefer encrypting my notes that are particularly personal.
