But as you see, larger period means less independent cycle groups. the outer worlds console commands item list

Is it possible to recover the seed used by Python

WebDec 9, 2024 · Is there a way to recover the seed or find the next 460 numbers in the sequence? The first thing to know is that Python's random module uses Mersenne Twister as the PRNG. That is not a cryptographically secure RNG, in fact it is easy to recover the state as long as you have enough samples.

WebJul 4, 2024 · Most pseudo-random number generators (PRNGs) are build on algorithms involving some kind of recursive method starting from a base value that is determined by an input called the "seed".

WebSo ask for 128 bits (16 bytes) and you will have a fine enough seed for your PRNG. (The "128" is traditional. Current technological limit for the richest of attackers is close to 2 75 operations, and unlikely to increase beyond 2 100 in the next two or three decades. "128" is considered elegant by cryptographers because it is a power of 2.)
