Ok, here's my try at an explanation
# Assume the message is this my $message = "me ss age"; # Use unpack to endcode the message one character at a time my @character_code_send = unpack("C*", $message); # You now have an array of ASCII values for each # character of the message. # If you want to send the encoded message you # must join all the element of the array # together first # No need to use join because " " does it for you my $secret = "@character_code_send"; # So what gets sent is this print "Message encoded = $secret\n"; # To decode the receiver has to split back out to an array my @character_code_received = split ' ',$secret; # And then use pack to decode each element back to string my $characters_received = pack("C*", @character_code_received); # To get the answer !! print "Message decoded = $characters_received";

I assume this is just a programming exercise and not a real attempt at encryption
