You can use the age tool to encrypt secrets based on ssh public keys.

Here's a small shell script I use https://github.com/mhitza/toolbox/blob/main/scripts/encrypt-...

    encrypt-for github_username file

That's handy and obviously a major security increase compared to sharing on Discord, but I feel compelled to quote the age README:

> Keep in mind that people might not protect SSH keys long-term, since they are revokable when used only for authentication, and that SSH keys held on YubiKeys can't be used to decrypt files.
