NISTTestSuiten
NISTTestSuiten is a software framework developed by the U.S. National Institute of Standards and Technology (NIST) to evaluate the quality of random number generators. The framework was first released in 2005 as part of NIST’s efforts to provide standardized testing for cryptographic applications. It has since become a de facto industry standard for assessing the statistical randomness of bit streams used in encryption, simulation, and digital communications.
The core of NISTTestSuiten consists of a battery of statistical tests that examine various properties of input
The framework is platform‑agnostic, written in ANSI C and distributed under a permissive license that allows
NISTTestSuiten has been widely adopted by government agencies, academic institutions, and industry contractors to certify random
