How to use Random Hex Generator

Set the byte length you need, and the tool generates a random hexadecimal string of that length, useful as an ID, seed, or salt.

Frequently asked questions

What length should I use for a security salt?

16 bytes (32 hex characters) is a common minimum for password salts; use more for cryptographic keys depending on your algorithm's requirements.

Is this tool free to use?

Yes. This tool is completely free to use with no daily limits and no signup required.

Can I generate more than one at a time?

Most ID generators here support a bulk mode — set the count and copy the whole list at once.
