# USE AT YOUR OWN RISK

# This script stops when it hits the correct 
# password (you'll see keytool's "New Password:" prompt)
# If it makes it through all permutations without a match, 
# then tweak your input. Oh, and it's not particularly fast.

# Note the empty strings at the end of each array to
# try leaving out those parts
