Parity -- of course!
Not to split hairs with Mr. Cooke, but 3DES is certainly much more than twice as secure as single DES, even if it does only provide 112 effective bits of encryption. More like 2^56 times more secure (against an exhaustive search).
Thanks, all, for your responses. Since our use of 3DES is pretty typical, I think it will be sufficient to tell marketing, simply, that we use Triple-DES. (If they come knocking, I'll be forced to tell them that it's a 168-bit algorithm that provides 112 bits of encryption. But do they really want to know that?)
