docker-credential-helpers VS rage

Docker supports a credential-helper module[0], which supports 4 different backends for fetching the docker registry credentials: osxkeychain, pass, wincred, and secretservice.

pass lets you use GPG-smartcards, and many of those (such as Yubikeys) will let you enforce touch-policies for signing/encruption.

As a combination of both these however, I must touch my Yubikey every time I pull a new docker image.

Another cool use-case is that I use the terraform-pass-provider to save secrets for my personal terraform project.

I have already built this into a small feature in my app, but I do plan to integrate it deeper and bake it into the core functionality soon. Which should be another interesting problem to solve as the app has integrated client-side encryption using Age (rage (rage-wasm)). But that's for another day...

I just added rage (https://github.com/str4d/rage) support, which does support pinentry, see https://github.com/anticomputer/age.el#known-issues for an example of how to use rage instead.

Really appreciate this article. It's a little snarky but it hits the mark and encourages people to try Age, which is a pretty awesome little tool.

I'm not convinced that whole-disk encryption is sensible for most threat models, but I use the built-in FileVault on macOS (under the reasoning that, at the very least, it can't really hurt).

On Linux, I use age[1] (specifically, rage[2]) to encrypt sensitive files. I wrote a secret manager that uses the latter as an encryption backend[3], and I use `rage-mount` to mount (read-only) views of encrypted archives.
