Re: Using sound cards to accelerate RSA?

Somebody mentioned the possibility of using the a/d stage of a sound card as a source of random bits, and that brought a thought back to mind: given that a lot of sound cards are now shipping with DSP chips on board, has anyone written any code that uses the cards DSP to accelerate RSA processing?

But most sound cards still don't have DSP chips. And modern general purpose CPUs are beginning to give them such a good run for their money that I wonder whether DSPs will ever become widespread. I'd stick with running RSA on the main CPU for now. Phil
