Blowfish Test Vectors with 16-Byte Keys

A tutorial Perl example is provided to show how to build a table of test vectors with Crypt::Blowfish with 128-bit (16-byte) secret keys.

I think we have a good understanding on the Crypt::Blowfish module now. Let's try to build a test vector table with 128-bit (16-byte) secret keys.

Here is my Perl script, which takes a list of secret keys and plaintext, then encrypts them one by one:

#- Crypt-Blowfish-16-Byte-Key.pl
#- Copyright (c) 2015 HerongYang.com, All Rights Reserved.
#- 
   use Crypt::Blowfish;

   @tests = split(/\n/, getInput());
   print("Blowfish 128-Bit Key Test Vectors in Hex:\n");
   foreach (@tests) {
      ($i, $keyHex, $plainHex) = split(/ +/,$_);
      $keyStr = pack("H*", $keyHex);
      $plainStr = pack("H*", $plainHex);
      $cipher = new Crypt::Blowfish($keyStr);
      $cipherStr = $cipher->encrypt($plainStr);
      $cipherHex = unpack("H*", $cipherStr);
      print("$i - Secret Key: $keyHex\n");
      print("   Plaintext: $plainHex -> Ciphertext: $cipherHex\n");
   }

sub getInput {
   return $input = << 'EOD';

Run the example script, you will get a nice looking Blowfish test vectors with 128-bit secret keys:
