Overview ¶
Package token is the gateway's credential check: which issuer it trusts, which audiences it accepts, and the keys it verifies against.
It is deliberately thin. The identity DECISION — what a claim means, which org a request acts in, who pays, which headers get minted — lives in hanzoai/authz and hanzoai/authz/edge, because three consumers each having their own reading of one contract is what drifted into a live escalation. What is left here is the part that is genuinely this deployment's: the ISSUER and AUDIENCE policy, named by the environment variables this deployment already sets.

Variables ¶
var DefaultAudiences = []string{
"hanzo-app",
"hanzo-console",
"hanzo-chat",
"hanzo-id",
"hanzo-admin-guard",
"admin-console",
"hanzo-world",
"cowork",
"https://api.hanzo.ai",
}
DefaultAudiences is the baked allowlist: the known IAM client_ids (each app's `aud` is its client_id) plus the API origin. Forwards-only — append a new client_id, never remove one. Override entirely with GATEWAY_ALLOWED_AUDIENCES.
var ErrNoToken = edge.ErrNoToken
ErrNoToken is the edge's sentinel, re-exported so a caller that already imports this package for its config can compare against it without importing the edge for one variable. It is the same value, not a copy.
Functions ¶
func AudiencesFromEnv ¶
func AudiencesFromEnv() []string
AudiencesFromEnv resolves the audience allowlist. GATEWAY_ALLOWED_AUDIENCES (comma-separated), when set, fully replaces the baked default. Otherwise the baked list is used, with the legacy single-value AUTH_AUDIENCE folded IN when set — it widens, never narrows, so a deployment still pinned to AUTH_AUDIENCE keeps that value inside an already-inclusive set rather than collapsing the allowlist to one entry. The result is never empty, so the check is always enforced.
func NewValidator ¶
NewValidator builds the edge's verifier from cfg. The check itself lives in hanzoai/authz/edge — this package's whole job is turning THIS deployment's environment into the values it takes, which is the only part that is ours.
Types ¶
type Config ¶
type Config struct {
JWKSURL string
Issuer string
// Audiences is the allowlist of acceptable `aud` values, with OR semantics: a
// token passes when its audience matches ANY entry.
//
// It is enforced HERE rather than in authz.Verify, which deliberately does not
// check audience — IAM sets `aud` per RFC 8707 to the requesting CLIENT, so the
// claim names which client asked for the token, not which resource server may
// accept it. Checking it is therefore a POLICY an edge may hold ("I accept tokens
// minted for these consoles") and not part of reading a token. An empty list
// disables the check; AudiencesFromEnv never returns empty, so it is always on.
Audiences []string
JWKSTTL time.Duration
}
Config is the edge's verification policy.
func ConfigFromEnv ¶
func ConfigFromEnv() Config
ConfigFromEnv reads the AUTH_* variables, so every binary in this module agrees on the IAM authority.
