Generators

Sometimes you need a fresh value on demand: a unique identifier for a database row, a strong password, a checksum to verify a download, a QR code for a link, placeholder copy to fill a mockup, or a cron expression for a scheduled job. These generators produce them instantly and, where randomness matters, use the browser’s cryptographically secure random source rather than a predictable pseudo-random one. Identifiers follow their specs (UUID v4 and the time-ordered v7), hashes come straight from Web Crypto, and every generator explains the trade-offs — entropy, collision odds, error-correction levels — so you can pick sensible options instead of guessing.
