Secure Random Generator

This tool generates cryptographically secure random numbers. Normally, computers use pseudo-random number generators that are fast but not totally random. The difference from real random data is usually not noticeable in common uses like simulated coin flips or dice rolls. However, when used in cryptography, usually to generate a new secret key, the deficiencies of a pseudo-random number generator can be exploited to predict which keys it will generate! This is why it's important to use secure random data, which uses a much slower algorithm or even a hardware device to generate truly unpredictable random numbers.
