Slow AES decryption in Android

Question

I tried to decrypt a 4.2 MB .dcf file using AES 128 bit key, but it took 33 seconds to decrypt (on function cipher.doFinal(data)), is it normal ?

Here is a code snip

Answer 1

AFAIK, there's no way to get access to the ARM chip's AES encryption/decryption hardware via the Android APIs :-(

This is a huge oversight on Google's part unfortunately...makes using AES on other platforms a LOT faster....
