lib.rs

1//! Security infrastructure for systemprompt.io.
2//!
3//! Houses the request-level authentication primitives shared by the HTTP
4//! API and the runtime layer:
5//!
6//! - Asymmetric signing key plane ([`keys`]) — the in-process `TokenAuthority`
7//!   holds the active RSA keypair, exposes the public set for
8//!   `/.well-known/jwks.json`, and caches federated JWKS documents under a
9//!   bounded LRU with an HTTPS allowlist.
10//! - JWT minting ([`jwt`]) for admin tokens and ([`session`]) for
11//!   session-scoped tokens. Tokens are signed RS256 via `TokenAuthority` and
12//!   carry a `kid` header; HS256 is rejected on validation.
13//! - Token extraction ([`extraction`]) from `Authorization` headers, MCP proxy
14//!   headers, and cookies.
15//! - Request validation ([`auth`]) that turns those tokens into a
16//!   [`systemprompt_models::execution::context::RequestContext`], resolving
17//!   non-self-issued tokens against `profile.security.trusted_issuers` and
18//!   propagating the RFC 8693 `act_chain` onto the per-request context.
19//! - At-rest hashing ([`at_rest`]) — `hmac_sha256` / `hmac_sha256_hex` under
20//!   the deployment `oauth_at_rest_pepper`, used to store refresh-token ids and
21//!   authorisation codes as digests rather than plaintext.
22//! - Google service-account credentials ([`google`]) — the RFC 7523 JWT-bearer
23//!   exchange that turns a service-account key into a Google OAuth access
24//!   token, with a process-wide token cache.
25//! - Bridge manifest signing ([`manifest_signing`]) with Ed25519 keys.
26//! - Lightweight scanner / bot detection ([`services`]).
27//! - Upstream-credential plane ([`credential`]) — a stored secret is parsed
28//!   once into a `ProviderCredential`, which answers for its own scope
29//!   (project, region, principal) and its own auth header; [`google`] is one
30//!   implementation of that model, not a credential story of its own.
31//!
32//! All public fallible APIs return typed errors from [`error`] and
33//! [`credential::CredentialError`] — `anyhow` is not used in any public
34//! signature.
35//!
36//! # Feature flags
37//!
38//! This crate has no Cargo features; everything compiles by default.
39//!
40//! # Example
41//!
42//! ```no_run
43//! use systemprompt_models::auth::JwtAudience;
44//! use systemprompt_security::AuthValidationService;
45//!
46//! # fn demo(headers: &axum::http::HeaderMap) -> systemprompt_security::AuthResult<()> {
47//! let svc = AuthValidationService::new("systemprompt.io".to_string(), JwtAudience::standard());
48//! let _ctx = svc.validate_request(headers)?;
49//! # Ok(())
50//! # }
51//! ```
