Random String & Cryptographic Salt Generator

Create high-entropy random character strings, salts, and nonces with custom charsets

100% Client-Side Cryptographic Processing

All passwords, passphrases, and entropy calculations use your browser’s native Web Cryptography API (`crypto.getRandomValues`). No passwords, phrases, or keys are transmitted across any network.Security Reminder: Client-side tools prevent network interception, but cannot protect against compromised devices (such as screen recorders, malware, or compromised browser extensions). Always use a dedicated offline password manager for critical master passwords.

Frequently Asked Questions

What is a cryptographic salt?

A salt is unique random data passed into a one-way hashing function alongside a password to protect against rainbow table lookup attacks.

What is the difference between random strings and passwords?

Random strings are designed for nonces, API tokens, CSRF verification tokens, and database salting where human readability is not required.

Does this use a CSPRNG or standard Math.random()?

This generator strictly uses window.crypto.getRandomValues, a cryptographically secure pseudo-random number generator (CSPRNG) seeded by system hardware entropy.
