About Random Base64
Random Base64 generates random bytes and encodes them as Base64 — a compact way to store random binary data as text.
It suits secrets, tokens, and test values placed in config files or environment variables. Its randomness comes from the browser CSPRNG.
If you need a URL-safe form (no +, /, =), use Random Token, which outputs Base64URL.
FAQ
Are my data or keys sent to a server?
No. Random Base64 runs entirely in your browser using the Web Crypto API and client-side libraries. Your data, passwords, and keys never leave your device.
