Crypto & Security Tools

Hash generators, password creators, JWT decoders, and token counters for security and authentication workflows — all running client-side in your browser. Generate MD5, SHA-1, SHA-256, and SHA-512 hashes for file integrity checks and password storage. Create strong, customizable passwords with length, character set, and entropy controls. Decode and inspect JWT tokens to debug authentication flows without exposing secrets to third-party websites. Count tokens for LLM API calls to estimate costs before sending requests. Every crypto tool processes data locally with zero server communication, making them safe for production secrets, API keys, and authentication tokens that should never leave your machine.

Frequently Asked Questions

Is it safe to paste JWTs and passwords into these tools?

Yes. All crypto and security tools run entirely in your browser with no server communication whatsoever. Your JWTs, passwords, and hashes are processed locally and never transmitted, logged, or stored.

Which hash algorithms are supported?

Our hash generator supports MD5, SHA-1, SHA-256, and SHA-512. All algorithms use the Web Crypto API built into your browser for reliable, standards-compliant hashing.

Can I use the password generator for production credentials?

Yes, the password generator uses cryptographically secure random number generation (crypto.getRandomValues) and runs entirely client-side. Generated passwords are never sent anywhere, making them safe for production use.
