Secure Web Token (SWT)

Secure Web Token (SWT) is a Node.js library offering a security-focused alternative to traditional JSON Web Tokens (JWTs). Unlike JWTs, which are merely Base64 encoded, SWT employs AES-256-GCM encryption for payloads and implements server-side session binding, making tokens device-bound and preventing reuse on other devices. This approach significantly enhances security by making stolen tokens useless for attackers. The current stable version is 1.2.8. It provides a simple API with `sign()` and `verify()` functions, supporting expiry and HttpOnly session cookies. Key differentiators include full payload encryption, true device binding, and server-side session management, making it suitable for high-security applications like admin panels, SaaS dashboards, and internal tools where preventing token leakage and session hijacking is critical.
