How to use Encryption Key Generator

Pick AES or RSA-sized key material and hex or base64 output, and the tool generates cryptographically random key bytes ready for use in your encryption workflow.

Frequently asked questions

Is this key generated securely enough for real encryption?

Yes. It uses your browser's cryptographically secure random number generator (Web Crypto API), the same source used for real encryption keys, not Math.random().

Is this generated securely enough to actually use?

Yes. Generation uses your browser's cryptographically secure random source (Web Crypto API), not a predictable pseudo-random function.

Does this tool send anything to a server?

No. Everything is generated entirely client-side in your browser — nothing you generate is ever transmitted anywhere.
