Crypt::X509 / Blessing error

Hi,

when i try to run this simple Crypt::X509 script, i have
this
error: "Attempt to bless into a reference at
/opt/perl_32/lib/site_perl/5.8.8/Crypt/X509.pm line 105."
I want to build a mailer to send alerts to our customer,
if they have to renew their certificates, the ldap
extraction is already running.
________________________________________
___________
use Crypt::X509;
#INITIALIZING
my $certfile="46B2D0D7.cer";
my $certificate;

open CERTFILE , $certfile or die "Error to open file";
binmode binmode
read (CERTFILE, $certificate, 65536);
close CERTFILE;

$decoded = new Crypt::X509->new( cert => $certificate );

print "Certificate Subject: ".$decoded->Subject;
________________________________________
___________

Does someone know what's wrong with this?

Thank you,
JL

Presumably that ought to be:

binmode CERTFILE;

?

What happens if you single-step with the perl debugger?

Cheers,

This happens in the following code:
sub new {
=09my ($class,%args) =3D @_;
=09if (!defined ($parser)) {
=09=09$parser=3D_init();
=09}
=09my $self =3D $parser->decode($args{'cert'});
=09
=09$self->{"_error"} =3D $parser->error;
=09bless ($self, $class); <=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Error comes down=
here
=09return $self;
}

This can only happen, when the given cert argument is not a string (or
scalar in Perl speak)

Like Chris already suggested, you probably give the new function an
undef, which leads to an uninitialised parser, that cannot be blessed.

Did the Tests work when you installed Crypt::X509 ? When you look in
the t subdirectory you'll find an example how to read a *binary*
certificate file and use the module.

You are calling new on the result of calling new

take out that first 'new'
