I'm following the instructions on the FAQ for setting up IPSec.
I've just got a simple question. When doing the following command:
dd if=/dev/urandom bs=1024 | sha1
As suggested in the FAQ, is it normal for a machine to "go out to lunch"
for several minutes? Like, 15 or more? I've never done this, and,
since I've not done any programming yet with encryption based
technology, I must admit to some ignorance as to what's really happening
in memory at this point. Is this normal behavior?
Also, where exactly does the output of sha1 go? I read the man page,
but all it says is that it's output is condensed message, or hash, of
it's input suitable for use as a digital signature. Where does it go?
