And also AES-128 10 round and AES-256 14 round. – T. Rifle Mar 11 '17 at 11:52 When looking to access a system, hackers will always go for the weakest point, which isn’t going to be the encryption whether it’s a 128 bit key or a 256 bit key. Therefore, it is more important to check that the software you are considering does what you want it to do, it protects your data in the way you think it does, and that there are no weaknesses in the processes. 2/4/2010 · NIST has concluded and recommended that all three key-lengths (128-bit, 192-bit and 256-bit) of AES provide adequate encryption until beyond calendar year 2031. NIST’s recommendation above includes the threat model not only of predicting the key, but also of cracking the encryption algorithm. According to different benchmarks AES 256 is not significantly slower than AES 128. I assume SA devs haven't implemented the encryption algorithm, but deligated this task to OpenSSL (or whatever library being used in SA17).

For XTS decryption, we see a 30% improvement for 256-bit XTS keys over 512-bit keys. Note that this is raw performance of the AES-NI instruction. A generic rule of thumb is that a larger key is more secure than a smaller one for a given algorithm. Surprisingly it's not true for AES. AES-128 is (at the time I write this) more secore than AES-256.

Briefly, there is a long-known problem with how AES deals with 256-bit AES keys. In normal use, AES keys are generated by a "truly" random source and never by a simple pseudorandom generator (like C++ rand ()); AES256 is "more secure" than AES128 because it has 256-bit key - that means 2^256 possible keys to bruteforce, as opposed to 2^128 (AES128). The numbers of possible keys are shown in your table as "combinations".
