Советы и лучшие практики
- crypto.getRandomValues is a CSPRNG (cryptographically secure) — suitable for secrets, salts, and tokens. Math.random is NOT.
- For passwords, prefer length over symbol-soup: 16 chars of [A-Za-z0-9] is stronger than 8 chars including symbols.
- For API keys, base64-friendly mode keeps the characters URL-safe and easy to copy.
- Tokens generated here are unique per call but not stored — copy yours immediately or regenerate.
- For server-side secret generation, prefer your platform's crypto library (openssl rand, secrets.token_hex, etc.) over a browser tool.
