About this plugin

When you need to verify message integrity or authenticate requests, an extra network call can mean unacceptable latency or a single point of failure. dsh-hmac packages HMAC (Hash-based Message Authentication Code) signing and verification into a dsh plugin, implemented in pure Node with zero external services and zero network calls—everything happens locally.

Its core capability is straightforward but solid: once registered in a session, you can immediately invoke HMAC tools to sign or verify any message without standing up additional infrastructure. Because it runs entirely offline, it fits naturally into air-gapped environments, CI pipelines, or any workflow where data must never cross a boundary.

Who is it for? If you maintain a dsh workflow and need integrity checks on API payloads, log excerpts, or key operations without pulling in external dependencies, dsh-hmac is a lightweight security building block. MIT-licensed, source-auditable, and ready to use right away.

Use Cases

  • Verify message integrity in air-gapped or intranet environments
  • Sign log excerpts in CI pipelines to prevent tampering
  • Authenticate key operations within a local session

Best For

  • Developers maintaining dsh workflows who need a local security building block
  • Intranet or compliance teams requiring data to stay within boundaries
  • Engineers seeking lightweight message signing without external service dependencies
