Notice that any DRBG needs a seed input, and that must be random and secret, thus best generated by a True RNG. WebJun 7, 2024 · As the size of the nonce may vary many libraries, usually the increase of the counter is done modulus $2^{128}$, with the disadvantage that an overflow in the lowest 32 bit will affect the nonce. It is usually up to the user of the AES library to test this (but you'd need $2^{32} * 16 = 64 \text{GiB}$ or almost $69 \text{GB}$ to get there). emphaze aex hybrid purifier
