SigningConfig class

Configuration describing signing keys and behaviour.

This object is typically produced via SigningConfig.fromEnvironment, which accepts the standard STEM_SIGNING_* environment variables used by producers and workers:

  • STEM_SIGNING_KEYS for HMAC secrets (keyId:base64 pairs)
  • STEM_SIGNING_PUBLIC_KEYS and STEM_SIGNING_PRIVATE_KEYS for Ed25519
  • STEM_SIGNING_ACTIVE_KEY identifying the key used for new envelopes
  • STEM_SIGNING_ALGORITHM (hmac-sha256 or ed25519)

Producers leverage this configuration through PayloadSigner and will emit warnings plus fail fast when signatures cannot be generated (for example, if the private key for the active Ed25519 key is missing).

Constructors

SigningConfig.disabled()
Disabled configuration (no signing).
const
SigningConfig.fromEnvironment(Map<String, String> env)
Parses config from environment variables.
