Frequently Asked Domande

Are the generated strings secure?

Yes. We use the Web Crypto API (crypto.getCasualeValues) a generate cryptographically secure random numbers. This is the same method used by modern browsers for TLS encryption.

Are strings stored anywhere?

No. Everything happens in your browser. Strings are not sent a any server and disappear when you close the tab.

What is entropy and why does it matter?

Entropy measures randomness in bits. Higher entropy means the string is harder a guess or crack. A 16-character string with all character sets has about 95 bits of entropy, which is very secure.

Can I use custom characters?

Yes. Enable the "Personalizzato Personaggios" option and enter your own set of characters. The generator will only use those characters.
