  my $key = pack H*, 00000000000000000000000000000000;
  my $plain_text = pack H*, 00000000000000000000000000000000;
  my $c = Crypt::Camellia->new($key);
  my $cipher_text = $c->encrypt($plain_text);

  use Crypt::Camellia_PP;
 
  my $key = pack H*, 00112233445566778899AABBCCDDEEFF;
  my $src = pack H*, FFEEDDCCBBAA99887766554433221100;
  my $camellia = Crypt::Camellia_PP->new($key);
  my $cipher_string = $camellia->encrypt($src);
 
  my $plain_string = $camellia->decrypt($cipher_string);
  $plain_string eq $src;



    With Crypt::CBC module



  use Crypt::CBC;
 
  my $cbc = Crypt::CBC->new({
      cipher => Crypt::Camellia_PP,
      key => pack(H*, 00112233445566778899aabbccddeeff),
      iv  => pack(H*, 00000000000000000000000000000000),
      literal_key => 1,
      header => none,
      padding => standard,
  });
  my $cipher_text = $cbc->encrypt(Hello World!);
  my $plain_text = $cbc->decrypt($cipher_text);
  $plain_text eq Hello World!;
