16 Sorry to pester you, but I'm beginning to realize just how much is
17 involved here that I'm a newbie at. Two more questions...
18
19 1) If multiple encryption algorithms are enabled in the kernel, how does
20 the system decide which one to use?
21
22 2) I assume that if I want to use the same encrypted USB key on 2 or
23 more machines, then the kernels of all the machines must be built with
24 the same encryption algorithms?
