in reply to RC4 question

I'm sure there has to be a better way to do this (read: this could be way off the mark), but assuming you're referring to Crypt::RC4, try the following:

use Crypt::RC4; my $key = "abcdefghijklm"; my $plaintext = "Hello, World!"; my $encrypted = RC4($key, $plaintext); print $encrypted, "\n"; my @characters; for (split //, $encrypted) { push @characters, ord($_); } print @characters, "\n"; $encrypted = ""; for (@characters) { $encrypted .= chr($_); } print $encrypted, "\n"; my $decrypted = RC4($key, $encrypted); print $decrypted, "\n";

This basically just uses ord to return the numeric values of the encrypted string and place them in @characters. Probably not what you're looking for, but it can't hurt (can it? ;). I'm also curious, why exactly do you want to do this?
