I might do something like this: 
$letter = 'a'; @ct = qw{ 11 41 71 };
$forward{$letter} = [ @ct ];
...


# Build reverse hash
foreach $letter (keys %forward) {
   foreach $ciphertext (@{$forward{$letter}}) {
      $reverse{$ciphertext} = $letter;
   }
}

print join(" ", @forward{split(//, "plaintext")});
print join("", @reverse{qw{ 19 59 71 75 77 63 13 66 33 }});
