AuthCallout.Identity

Identity primitives from nats-auth-callout-service, a NATS auth callout that validates OIDC tokens and mints scoped NATS user JWTs.

A subscriber uses this package to verify the signed Callout-Identity header a client attaches to its messages (ADR 0010/0011):

  1. Read the assertion from the message header named in the app's discovery descriptor.
  2. Read its kid header and fetch the public key from the callout_assertion_keys KV bucket (cache it per kid).
  3. Verify with AssertionSigner.Verify(compactJwt, publicKey). It returns AssertionClaims, or null for a bad signature or malformed token.
  4. Reject when claims.Expiry is in the past.
using var signer = new AssertionSigner([new ResolvedAssertionKey("verify-only", throwawaySeed, Active: true)]);
AssertionClaims? claims = signer.Verify(headerValue, publicKey);

AssertionSigner needs one active key in its keyset even when you only verify; a throwaway, never-used NKey satisfies it. The repo's dev/samples/Shared shows the full client and subscriber flow (discovery, self-assertion fetch, verification, OIDC token resolution).

Also contains the service's OIDC TokenValidator and JWKS cache.
