No backend involved — all data is encrypted/decrypted in-browser using the Web Crypto API.
Support for Hex, Base64, and Raw Keys
Accepts multiple secret key formats for flexible developer workflows.
Minimal, Developer-First UI
Focused interface for quick input, formatting, and secure results — designed with developers in mind.
Built-in Format Validator (iv:data)
Enforces correct structure and warns users on invalid input before decryption.
Dark Mode & Responsive Design
Fully responsive, accessible UI with modern dark theme support.
