Random String Generator FAQs
Common questions about generating random strings
How random are the generated strings?
The strings are generated using JavaScript's Math.random(), which uses a pseudo-random number generator. While not cryptographically secure, it provides sufficient randomness for most applications like passwords, tokens, and test data.
What is the maximum length I can generate?
The tool supports generating strings from 1 to 256 characters in length. This range covers most use cases while maintaining good performance.
Can I generate strings with only specific characters?
Yes, you can customize which character sets to include: uppercase letters, lowercase letters, numbers, and symbols. You can select any combination of these sets.
Are the strings cryptographically secure?
The generated strings use JavaScript's Math.random(), which is not cryptographically secure. For cryptographic purposes (like generating encryption keys), you would need a cryptographically secure random number generator.
Is my data sent to a server?
No, all string generation is performed client-side in your browser. Your preferences and generated strings are not sent to any server, ensuring privacy and security.
Can I see statistics about the generated string?
Yes, the tool displays real-time statistics showing the length, number of uppercase letters, lowercase letters, numbers, and symbols in the generated string.
What happens if I uncheck all character sets?
If all character sets are unchecked, the generator will not be able to create a string and will display an empty result. At least one character set must be selected.
