Summary
CoolTest is a new randomness test designed to work well with small amounts of data, published in November 2026. Randomness tests check whether data appears truly random or follows a pattern, which is important for security applications like cryptography (the practice of encoding information to keep it secret). This tool addresses a limitation of existing tests that often require large datasets to work accurately.
