Do mobile devices have enough CPU to support HTTPS for all of a website's traffic?

Question

We are developing a web application intended for use on smartphones and other mobile devices, and we are thinking about running all traffic through HTTPS to make security simpler.

I know that the CPU cost of HTTPS encryption for bigger computers is fairly trivial, but is this also true for modern smartphones like iPhone and Android?

Answer 1

Considering that the cpu of such a device runs at 400 MHz or higher, and that https has been around for decades running on slower cpu's, I'd say there is no problem with that.
