About this tool
Set a length and this tool builds a string from the sixteen hexadecimal characters, digits 0 to 9 and letters a to f, picked at random. Hex strings like this are common as test tokens, colour values and example identifiers. The output is random text only; it is not a secure secret and should not be used as a password or key without a proper generator.
Frequently asked questions
Can I use the output as a password?
No. It is made with a basic random function for examples and tests, not with a security-grade generator.
What characters can appear?
Only 0 to 9 and a to f, the sixteen hexadecimal characters.
