You enter
32 bytes, hex format
The tool shows
A 64-character random hex string (32 bytes = 256 bits)
32 bytes (256 bits) of randomness is a common choice for signing keys and API tokens and is the default here. Even 16 bytes is out of reach for guessing if the source is truly random.
Both encode the same random bytes. Hex uses 2 characters per byte, while base64url is about a third shorter and is safe in URLs and headers because it avoids plus, slash and padding.
No. Math.random is predictable and not meant for security. This tool uses crypto.getRandomValues, the browser cryptographic random generator.
Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
