Greetings, fellows.

I'm trying to do some basic operations using Crypt::Blowfish here, but I'm not getting it too good as I thought I would.

This module looks very simple to use, but I'm missing something here.

I was sucessfull to encrypt a string but can't decrypt it. I've followed the module documentation and did like this:

To encrypt: 
#!c:/perl
use Crypt::Blowfish;

while ($pass = <>)
{
    chomp $pass;
    $key = pack ("H16","0123456789ABCDEF");
    $cipher = new Crypt::Blowfish $key;
    $ciphertext = $cipher->encrypt("$pass");
    print unpack ("H16",$ciphertext),"\n";
}

and, to decrypt: 
#!c:/perl
use Crypt::Blowfish;

while ($pass = <>)
{
    chomp $pass; 
    $key = pack ("H16","0123456789ABCDEF");
    $cipher = new Crypt::Blowfish $key;
    $ciphertext = $cipher->decrypt("$pass");
    print unpack ("H16",$ciphertext),"\n";
}

So, if I try to put the encrypted string for the module to decrypt it, it returns this:

"input must be 8 bytes long at C:/Perl/site/lib/Crypt/Blowfish.pm line 68, <> line 1"

Can anyone explain this to me? Why it doesn't works? If it must be 8 bytes long why does it generate a longer string?

Thanks in advance, brothers.
