Random Line Picker: Draw From Any List The Random Line Picker selects one or more lines from a list using a cryptographically secure random source — suitable for fair draws, random sampling, and test data selection. The W3C Web Cryptography API specification defines , the cryptographically secure entropy source used by this tool. The rejection sampling algorithm that achieves uniform selection is covered in NIST SP 800-90A on random bit generation. --- Why Cryptographic Randomness Matters? Most programming environments provide two levels of random number generation: / — fast, but pseudorandom. The sequence is reproducible given the same seed and is not suitable for fair draws or security purposes. * — cryptographically secure pseudorandom number generator (CSPRNG). Draws from OS entropy…
Frequently Asked Questions
How do I pick a random item from a list?
Paste your list (one item per line) into the Random Line Picker tool and click Pick. A random line is selected and highlighted. Click again to pick a different one without removing the previous result.
How do I draw a winner from a list?
Paste all participant names — one per line — and click Pick. The tool uses crypto.getRandomValues() for an unbiased draw. You can pick without replacement by enabling Remove After Pick, so each winner is removed from the pool.
How do I sample lines randomly without replacement?
Enable Remove After Pick. Each time you click Pick, the selected line is removed from the list. Continue clicking until you have the desired number of unique winners or samples.
Is browser random truly random?
The tool uses crypto.getRandomValues() which is a cryptographically secure pseudorandom number generator (CSPRNG). It is unpredictable and not reproducible. Math.random() — which many sites use — is not cryptographically secure and should not be used for fair draws.
How do I pick multiple random lines?
Set the Pick Count field to a number greater than 1 before clicking Pick. The tool selects that many unique lines at once without replacement. Alternatively, enable Remove After Pick and click multiple times.
