"WebFeb 12, 2024 · The benefit of re-seeding your DRBG should be clear: If the state of your DRBG gets compromised at any point, an attacker can re-compute all the outputs of the DRBG following up until the last reseed which limits the damage in case of an successful attack. Now for the question you may have: Can a re-seed hurt security? " - Ctr_drbg with derivation function
