Re: Get a grip!
"I am getting the grip. Most ARM chips have AES acceleration and libraries to use it."
No they most certainly do not. Of the last 10 ARM CPU's that I have designed into embedded devices, only one had any (claimed) encryption support - and when I tried to use it I discovered that there was a silicon bug that meant that most of its functions did not work. I have implemented software encryption (both DES and AES), which causes a significant hit in file transfer speed.
