What is this tool?

A collection of cryptographically secure random generators. All values are generated client-side using the Web Crypto API (crypto.getRandomValues), meaning nothing is sent to a server.

Available generators

• UUID — version 4 (random) and version 7 (time-ordered) UUIDs per RFC 9562
• Password — configurable length with uppercase, lowercase, digits, and symbols
• Secret Key — hex-encoded cryptographic keys in common sizes (128, 256, 512 bit)
• Hex String — random hexadecimal strings of any length
• Base64 — random Base64-encoded tokens
• Number — random integers within a custom range
• Lorem Ipsum — placeholder text by paragraphs, sentences, or words

Common use cases

• Generating UUID primary keys for database records
• Creating secure API keys, tokens, and BETTER_AUTH_SECRET-style secrets
• Generating strong passwords for new accounts or services
• Filling mockups and prototypes with placeholder text
