although that is a concern, the greater risk is that this requires the
password to be stored in a shell-script, as plaint-text.

	"IDEA's key length is 128 bits - over twice as long as DES.
	 Assuming that a brute force attack is the most efficient,
	 it would require 2^128 (10^38) encryptions to recover the
	 key. Design a chip that can test a billion keys per
	 second an throw a billion of the them at the problem,
	 and it will still take 10^13 years - that's longer than
	 the age of the universe. An array of 10^24 such chips can
	 find the key in a day, but there aren't enough silicon
	 atoms in the universe to build such a machine. Now we're
	 getting somewhere - although I'd keep my eye on the dark
	 matter debate."
