No, but what packet sniffers _do_ require is to be running on a box that is
within the route from you to your host. 

Provided the criminal hacks a machine within your route, say your ISP or a
backbone router, and sniffs an IP address likely to obtain credit card
numbers, what he would obtain are number encrypted at your applet. Each
different applet would use a different key for encryption.

This doesn't make gaining these numbers impossible, just unlikely and
difficult. The idea being to make it more costly to gain the numbers than
can be gained with them.
