veltro-suite-auth

Veltro-owned suite session and service-token contracts with signed-realm compatibility.

This package is derived from the AGPL-3.0-or-later veltro-suite-auth 1.3.0 implementation originally maintained in VectorFlow. See NOTICE for provenance.

Authority envelope v2

verify_authority_envelope_v2 verifies and consumes short-lived ES256 veltro-suite-service+jwt envelopes. The receiver supplies the exact issuer, exact audience, active generation, that audience's public P-256 JWK ring, required scope, and an atomic synchronous or asynchronous replay consumer. The consumer runs exactly once after all stateless checks and must return literal True.

This package deliberately provides no v2 minting/signing API, private-key type, key generator, JWKS/network fetcher, settings/environment adapter, or consumer runtime wiring. Existing HS256 v1 compatibility remains separate and unchanged.

Browser request assertion verifier

verify_browser_request_assertion verifies and consumes short-lived ES256 veltro-browser-request+jwt request assertions minted by Veltro identity. The receiver supplies the exact issuer, exact audience, active generation, that audience's public P-256 JWK ring, the request being authorized (request with method and path), and an atomic synchronous or asynchronous replay consumer.

The verifier enforces every binding the mint records: exact typ, alg=ES256 allowlist, audience key ring and kid, signature, issuer/audience, active generation, nbf/iat/expiry capped at 60s, fixed realm default, grant-product consistency, and — the point of the artifact — that the signed method and canonical path match the request being authorized, using the same shared normalize_request_path contract the mint uses. An assertion minted for GET /chad/api/alerts never authorizes POST /chad/api/rules.

One-use semantics are the receiver's: after all stateless checks, the verifier calls the replay consumer exactly once with a frozen {issuer, audience, generation, jti, expires_at} tuple. The consumer must return literal True only if it has not previously seen that tuple; a replayed jti is rejected when the consumer returns False. The consumer must persist at least {issuer, audience, generation, jti} until expires_at to enforce one-use semantics across the token's validity window.

This package deliberately provides no request-assertion minting/signing API, private-key type, key generator, JWKS/network fetcher, settings/environment adapter, or consumer runtime wiring.
