+> **Development moved to [encryption4all/postguard](https://github.com/encryption4all/postguard), under `cryptify/`.**
+> That repository builds the crate as a workspace member sharing a single lockfile with `pg-core`/`pg-pkg`. Open issues have moved there too.
+> This repository is kept for history and will be archived once its Docker publish pipeline cuts over to `postguard`. Until then, this repository's CI is still the only publisher of `ghcr.io/encryption4all/cryptify` — do not remove its build/push steps yet.
