Convert Certificate from PEM to DER

Convert a PEM formatted certificate file (.cer, .crt, .pem) to DER format (.cer, .der). The Chilkat certificate class/object is a freeware component that is included in many of the Chilkat downloads.

Chilkat Module for Perl 5.8.*

Chilkat Module for Perl 5.10.*

use chilkat;

$cert = new chilkat::CkCert();

#  LoadFromFile will load either PEM and DER formatted files.
#  It automatically recognizes the file format based on the
#  file contents.
$success = $cert->LoadFromFile("chilkat.crt");
if ($success != 1) {
    print $cert->lastErrorText() . "\n";
    exit;
}

print $cert->subjectDN() . "\n";

$success = $cert->ExportCertDerFile("chilkat.der");
if ($success != 1) {
    print $cert->lastErrorText() . "\n";
    exit;
}

print "success!" . "\n";
