Is this truly random?

Uses Web Crypto API for cryptographically secure pseudo-random numbers.

Random vs pseudo-random?

True random uses physical phenomena. Pseudo-random uses algorithms. Crypto-secure is sufficient for most uses.

Can I generate test data?

Yes. Generate random numbers for test data, simulations, and statistical sampling.

What is the difference between Math.random() and crypto.getRandomValues()?

Math.random() uses a pseudo-random algorithm that is predictable and not suitable for security. crypto.getRandomValues() uses the operating system's entropy source for cryptographically secure random numbers.

How do I generate a random number within a specific range?

To generate a random integer between min and max (inclusive): Math.floor(Math.random() * (max - min + 1)) + min. For cryptographic use, use crypto.getRandomValues() with modular arithmetic.

About Random Data Generator

This tool generates random test data for development, testing, and demonstration purposes.

All data is randomly generated and does not represent real people or entities.

Note: Credit card numbers are randomly generated and are NOT valid for transactions. They follow the format but fail checksum validation.
