Ask HN: Why isn't there an AES512 or AES1024
Yes, I know AES/Rijndael is a symmetrical encryption algorithm that somehow became the winner of a competition NSA had a lot of strings to pull. In the same time it is considered relatively secure for most application. Our hard drives are most likely encrypted with AES128.
For super military+ grade why isn't there an AES512 or 1024 ?

- andreareina 9y agoIt's infeasible to brute-force a 256-bit key[1]. Where cryptanalysis lowers the size of the job enough that it's feasible, the answer isn't to have a bigger key, it's to have a better algorithm.
