WebAES has two steps that work together to thwart a known-plaintext attack. The actual round key and sbox steps simplified for explanation purposes would be something like for key k, ciphertext z = sbox (a * k) where the sbox is a simple substitution through a lookup table. Every byte is replaced with the corresponding byte from the table. WebAug 1, 2024 · AES, RSA and DH keys are all used for different purposes. When creating a protocol or when configuring your software it does make sense to use relating key sizes. So you would use symmetric keys of 128 bit or over, RSA keys of 3072 bits or over and ECC keys (and hashes) of 256 bits or over to achieve an overall strength of 128 bits.
