Tiny Systems Crypto Module

Cryptographic operations for Tiny Systems flows: self-signed TLS certificates, hash/HMAC digests, and inbound webhook signature verification.

Components

Component Description
cert_generate Generate self-signed TLS certificates with SANs. Use for K8s admission webhooks, internal HTTPS servers, or any TLS endpoint.
hmac_verify Verify inbound webhook signatures — GitHub (X-Hub-Signature-256), Stripe (Stripe-Signature with replay window), or generic HMAC-SHA256/SHA1 (hex or base64). Emits {valid, reason} for routing; constant-time comparison.
hash Compute sha256/sha512/sha1/md5 digests (hex or base64), plain or HMAC-keyed. Use for dedup keys, content fingerprints, and signing outbound webhook payloads.

  --set controllerManager.manager.image.repository=ghcr.io/tiny-systems/crypto-module
