WebOct 12, 2024 · This is the most widely used pseudorandom number generator (PRNG). We focus on the version MT19937, which has a period of 2^19937−1. It is used by default in many libraries and programs such as PHP, Python, Ruby, Microsoft Excel, and many more. Note that even though Python uses MT19937 internally, we reimplement it in pure Python. WebOften a pseudo-random number generator (PRNG) is not designed for cryptography. Sometimes a mediocre source of randomness is sufficient or preferable for algorithms that use random numbers. Weak generators generally take less processing power and/or do not use the precious, finite, entropy sources on a system.
