我作了aes的速度测试

----------------------------------------------------------------------------------------------------------------------------------------

1000s of bytes per second processed 是什么意思 ？每秒处理多少k字节？比如

aes-128 cbc 这一行的结果是什么意思？AES128不就是每次加密一块：128bit == 16bytes 吗？后面的 64 bytes 256 bytes 1024 bytes 8192 bytes 是什么意思？
