Keeper is an embedded cryptographic secret store for Go that encrypts data at rest using Argon2id key derivation and XChaCha20-Poly1305 authenticated encryption. It provides three interfaces: a Go library, HTTP handler, and CLI tool—all supporting four security levels and per-bucket DEK isolation. Originally designed for the Agbero load balancer, it works independently in any Go project.
