Cipher stream did not contain IV or salt

Hi List,


I am getting this error when i calling a cryptcookie.pl script from my
index.cgi that use Crypt::CBC and MD5.

[Fri Jun 17 11:30:31 2005] [error] [client x.x.x.x] Premature end of
script headers: index.cgi
[Fri Jun 17 11:30:31 2005] [error] [client x.x.x.x] Cipher stream did not
contain IV or salt, and you did not specify these values in new() at
libs/cryptcookies.pl line 24

--------------------------cryptcookies.pl---------------------------------
use MD5 ();
use Crypt::CBC;

use strict;
use vars '$CIPHER';

require "libs/checksum.pl";

$lib::crypt::cryptcookies::secret = "polkka";

$CIPHER ||= Crypt::CBC->new($lib::crypt::cryptcookies::secret, 'Blowfish');

## args: data to be encrypted and checksummed
sub encryptcookie {

        my $checksum = &newchecksum($lib::crypt::cryptcookies::secret, @_);

        return $CIPHER->encrypt_hex(join(':', $checksum, @_));
}

## 0: encrypted cookie
sub decryptcookie {

##24 my($checksum, @values) = split(/:/, $CIPHER->decrypt_hex($_[0]));

        if(&verifychecksum($lib::crypt::cryptcookies::secret, $checksum,
@values)) {
                return @values;
        }

        return undef;

}


1;
---------------------------------------------------------------------------

I did install MD5 and Crypt::CBC. What will be the problem ?

Thanks,
KetVin
