Generators_
Generators produce the artifacts you need on demand: version-4 UUIDs in bulk, passwords and passphrases, secret keys at the length the algorithm actually requires, MD5, SHA-256 and bcrypt digests, htpasswd lines, signed JWTs, QR codes, cron expressions and MAC addresses. Where randomness matters these tools use the browser’s cryptographically secure generator, seeded by your operating system, and say so plainly rather than blurring the line with "true randomness" marketing. Where a fast hash is the wrong tool — passwords, most obviously — the page says that too instead of generating it quietly.
