WebNow, concrete answer to your question is that the seed collision probability is AT LEAST equal to MINIMUM of seed space and PRNG period, or in more strict math terms: P <= 1/min (2^seed_bits, PRNG_period) (at least if each seed value maps to different internal state). But as you see, larger period means less independent cycle groups.

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.)
