The "Synchronizer Token Pattern"—the standard approach to CSRF protection for the last decade—is becoming an architectural liability. In an era of serverless runtimes, edge computing, and distributed systems, relying on a stateful session store (like Redis) just to validate a form submission is an inefficiency we should no longer accept.
I am developing Sigil, not as another middleware framework, but as a stateless cryptographic primitive. It redefines CSRF protection from a "token check" into a mathematical verification of Request Intent.
This article details the engineering constraints, the cryptographic architecture, and the specific security pain points Sigil addresses without the bloat of traditional frameworks.
