WebApparently, the pseudo-random numbers that the random module generates are not cryptographically secure. Python uses Mersenne Twister algorithm for generating random numbers. But this algorithm is completely deterministic, making it an unsuitable choice for cryptographic purposes. WebBy default, the .NET Framework uses the system clock to generate the seed value for the random number generator. If the system clock is initialized with the same value during each run or the generator is being reinitialized with the same seed value, it's possible for the generator to produce the same sequence of random numbers each time.
