Here is my code. This is my first time using modules and I'm confused. It's supposed to print input to output. 
#!/usr/bin/perl -w
use strict;
use diagnostics;
print "Enter some text: ";
my $text=<STDIN>;
chomp($text);
my $key=pack("H16","0123456789ABCDEF");
my $cipher=new Crypt::Blowfish $key;
my $ciphertext=$cipher ->encrypt($text);
while ($plaintext) {
        print "$ciphertext\n";
}

uncaught exception from user code: input must be * bytes long at /usr/local/lib/perl5/site_perl/5.005/i386-freebsd/Crypt/ Blowfish.pm line 51, <STDIN> chunk 1. Crypt::Blowfish::encrypt(`Crypt::Blowfish:Hash(0x804e054)' ,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' ) called at ./bfencryptout line 10.

It's not a bug-it's an undocumented feature :D
