PRNG - Pseudorandom number generator, A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers that approximates the properties of random numbers.
This tag is for questions pertaining to random numbers and their generators, whether pseudo-random or truly random.
Non-random behaviour reflection
"Then you use it as seed in random which is less good that one is a non-cryptographic prng and its output may exhibit some structure which will not register in a statistical measurement tool but might be exploited by an intelligent attacker"
from question "High quality, simple random password generator"
"The non-random random behaviour is more a reflection on the quality of the rand prng â it is often not very good"
from question "PRNG program failure. Cannot enter random amount of choices and will always answer with 2 from the PRNG"
"But a large period prng takes up more memory for maintaining the internal state and also takes more time for generating a random number due to complex transitions and post processing"
