Questions about this tool family
Is every random generator safe for secrets?
No. Security-sensitive values need a cryptographically secure random source. Decorative or test-data generators can use weaker methods.
Can generated values collide?
Yes. Collision risk depends on the value space, distribution, and number of generated values. Use enough entropy for the task.
