Security Tools
Cryptographically secure tools that run in your browser. Generate strong random passwords, calculate SHA hashes, and never trust the network. All security operations use the Web Crypto API (window.crypto), the same standard that powers browser TLS.
Password Generator
popularGenerate strong, random passwords with customizable length and character options.
Hash Generator
newGenerate SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text.
About these tools
Security tools that use cryptographically secure randomness. A password generator that uses Math.random() is dangerous because the output is predictable. These tools use window.crypto.getRandomValues for password generation and window.crypto.subtle for hashing — the same APIs your browser uses for TLS. Generated passwords and hash inputs never leave your device.
