Are the generated license keys secure?

Yes, keys are generated using cryptographically secure random values in your browser. No data is sent to any server, ensuring complete privacy.

Can I use these keys for commercial software?

This tool generates random strings that can be used as license keys, but you should implement proper validation and security in your own licensing system. Consider adding checksums or encryption for production use.

What character sets are available?

You can include uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). Custom character sets are also supported.

How many keys can I generate at once?

You can generate up to 1000 keys in a single batch. For larger quantities, generate multiple batches.
