intigin 1.0.3

Intigin dynamic-backend adapter — thin in-app WSGI middleware for view-source protection.

intigin

Thin in-app WSGI adapter for Intigin dynamic-backend protection. It wraps your app so the same Intigin bundle that protects static sites also protects your server-rendered pages — view-source shows only a loader shell, and the real HTML is reconstructed client-side.

The adapter does almost nothing: the browser bundle does the heavy lifting. On a page navigation it returns a clean loader shell (no payload, no cookie); when the bundle asks for the page (a same-URL fetch carrying an X-Intigin-Payload header) it encodes the finished HTML into the frozen wire format and returns it. The bundle at https://{host}/{token}.js decodes and reconstructs the page, then reveals, polls, and hot-swaps live like a static Intigin page — no backend round-trip on updates.

Install

pip install intigin

Use

Wrap your WSGI callable with a scoped Gateway API key (dashboard → Settings → Gateway API). The adapter resolves your public bundle token from the key once at boot, so no token is hardcoded:

from intigin import Intigin

app.wsgi_app = Intigin(app.wsgi_app, api_key="iga_...", host="intigin.com")   # recommended

Flask uses app.wsgi_app; Django wraps application in wsgi.py. A raw 32-hex token="..." is also accepted for a zero-config demo.

Behavior

• Cookieless. The payload rides the bundle's marker fetch (the browser's own session), so nothing payload-related appears in the source and no cookie is set — cookie blockers don't affect it.
• Non-HTML passes through untouched; only top-level HTML navigations are wrapped.
• Fail-closed. A bad/missing key or any wrap error disables the adapter (serves your app unprotected, logged to stderr) or returns a self-contained restricted page — never the raw HTML for a failed encode.
• Kill-switch. INTIGIN_ADAPTER_MODE=wrap|passthrough|off (env). passthrough/off removes the adapter from the path.

Conformance

python -m intigin --selftest

Verifies the frozen wire format — base64("IGP1" + FLAGS + BODY), BODY = xor(deflate(utf8(html)), sha256(token)) — against the browser bundle's decoder.

Concealment, not encryption. The scramble key is derived from the public bundle token, so this defeats view-source and naive scrapers, not cryptanalysis. Object-level authorization stays in your own routes.
