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.) WebMar 5, 2024 · Step Three: Choose a Seed Starting Container.

Same Seed in Pseudo-Random Number Generator (PRNG)

WebJul 16, 2011 · One common pitfall using time to seed a PRNG is that the time doesn't change very often. For example on windows most time related functions only change their return value every few milliseconds. So all PRNGs created withing that interval will return the same sequence.
