Über Zufälliger-Zeichenkette-Generator

This tool generates cryptographically secure random strings using your browser's built-in random number generator (crypto.getRandomValues). No data is sent to any server. Perfect for API keys, session tokens, test data, and secure passwords.

Häufig gestellte Fragen

Are the generated strings secure?

Yes. We use the Web Crypto API (crypto.getZufälligWerts) to generate cryptographically secure random numbers. This is the same method used by modern browsers for TLS-Verschlüsselung.

Are strings stored anywhere?

No. Alles happens in Ihrem Durchsuchenr. Zeichenkettes are not sent to any server and disappear when you close the tab.

Was is entropy and why does it matter?

Entropie measures randomness in bits. Higher entropy means the string is harder to 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 "Brauch Zeichens" option and enter your own set of characters. The generator will only use those characters.
