Random Number Generator
You can use the random number generator below to produce numbers within a specified range. Use the menu options to select the type of number you wish to output.
To generate truly random numbers, you must use external hardware that detects randomness in physical processes. For example, there are many generators that detect noise in temperature, light, sound, or other quantum phenomena and use these signals to produce a sequence of completely random numbers. Several manufacturers make entropy keys that can be plugged into a USB drive. Serious online gaming websites rely on such hardware-based RNGs to prevent players from predicting which cards are dealt.
