http://duoduokou.com/cplusplus/27020777697354667080.html WebJan 2, 2016 · With AES, like most modern block ciphers, the key size directly relates to the strength of the key / algorithm. The higher the stronger. Since all bits are used, there are 2 k l e n possible keys, taking 2 k l e n 2 operations to brute force on average. For AES the internal key schedule and the number of rounds are different for each key size.
