in reply to Encryption/Decryption Program:

An example little filter. Don't forget to specify the secret key when encoding. :-)

use List::Util q(shuffle); use Getopt::Std; getopts('ds:'); $opt_s and srand $opt_s; @T{@$_} = shuffle @$_ for ([A..Z],[a..z]); $opt_d and %T = reverse %T; s{.}{$T{$&}//$&}eg, print for <>;

Now, could someone please determine if a pair of keys exist that cancel each other (decode without -d, that is)?
