About Security & ID Generators
Security and ID Generators has 42 tools for creating secrets, identifiers and test data. The Strong Password Generator and bulk password tool let you choose length and character types, and they show the exact entropy of the result. The UUID Generator makes version 4 and time-ordered version 7 IDs, with ULID, Nano ID, ObjectId and CUID-style IDs alongside. API keys, encryption keys, TOTP secrets and RSA key pairs are generated with the Web Crypto API.
For developers and testers there is fake data: names, addresses, emails, phone numbers, IP and MAC addresses, plus check-digit-valid barcodes, ISBNs, IBANs and VINs for form validation. The Test Credit Card Number Generator makes Luhn-valid numbers for payment sandboxes only. All randomness comes from your browser's cryptographic generator, and nothing you generate is sent over the network or stored.
