Header-only C++ library; CMake config package; zero-coupling files lifted from fewo-webapp: interceptor/SecurityHeadersInterceptor.hpp interceptor/BodySizeLimitInterceptor.hpp handler/JsonErrorHandler.hpp util/RateLimiter.hpp util/TokenExtract.hpp (extractToken, isValidIp, clientIpTrusted) startup/RequireEncryptionKey.hpp fewo-specific couplings (bindAddress global, fewo::config) replaced with explicit function arguments so the library stands alone. AuthInterceptor + requireAdmin deferred to v0.2 — they need IAuthBackend / IAuthPolicy / IRuntimeConfig seams designed first. docs/security-baseline.md ships CSP / rate-limit / body-size / encryption key constants as language-neutral baselines for non-C++ consumers.

oatpp-authkit
Header-only C++ library distilled from fewo-webapp's hardened auth / security stack. Header-only, oatpp 1.3+, C++17.
What's in v0.1 (the clean-lift set)
| Header | Purpose |
|---|---|
interceptor/SecurityHeadersInterceptor.hpp |
CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. Strict defaults. |
interceptor/BodySizeLimitInterceptor.hpp |
Reject request bodies above a configurable limit with 413 before they hit your handlers. |
handler/JsonErrorHandler.hpp |
Normalises thrown exceptions into {status, message} JSON so controllers never leak raw HTML error pages. |
util/RateLimiter.hpp |
In-memory token-bucket keyed on an arbitrary string (typically the client IP from clientIpTrusted). |
util/TokenExtract.hpp |
extractToken (Cookie/Bearer), isValidIp (IPv4/IPv6 via inet_pton), clientIpTrusted (loopback-gated XFF). |
startup/RequireEncryptionKey.hpp |
requireEncryptionKey(envVarName, encryptionEnabled, allowPlaintext) — refuse startup without a symmetric key unless a dev flag overrides. |

Roadmap
- v0.2 —
AuthInterceptor+requireAdminported onto three seams (IAuthBackend,IAuthPolicy,IRuntimeConfig) so consumers plug in their own user store, public-path list, and admin role set without forking the interceptor. - Later — session cookie helpers, API-key rotation, re-encryption migration.
See docs/security-baseline.md for language-neutral CSP / rate-limit / body-size
constants that non-C++ consumers can re-implement directly.
