Cryptographic keys

I have three kinds of keys at the moment: good old PGP/GPG keys that are mostly used to sign git commits, minisign keys that are used to sign software (being phased out), and sigstore keys that are used to sign software (being phased in).

GPG keys

These have an expiration date. I initially did 1-year keys, but that was too much trouble, so in 2015 I decided to use 10-year keys, possibly with more short-lived subkeys.

The keys are also available on public keyservers, e.g.:

Current key: passcod06 (2015–2025)

Minisign keys

In minisign format, used for signing software binaries.

Sigstore keys

In sigstore/cosign format, used for signing artifacts (software binary releases, container images, etc).

Eventually this will disappear as keys move to be ephemeral and generated against my identity, but in the meantime you can use this key to verify artifacts, along these lines:

$ cosign verify \
  -key https://passcod.name/info/keys/cosign.01.pub \
  ghcr.io/org/repo:version_target.ext
