I want to parse a X.509 certificate in php.
The certificate is in DER-encoded X.509 format.
I tried using openssl_x509_parse method
in php, but its not working.
The certificate data is a valid data received after firing a command in mdm for CertificateList.
I am using the below code:
$data = 'MIIDizCCAnMCCQDCpCAUbA2P4TANBgkqhkiG9w0BAQUFADBrMSIw

$fp = fopen('cert.txt','w+');
fwrite($fp, 'data=>'.openssl_x509_parse($data,true));
fclose($fp);
Well your certificate is missing the PEM-enclosing. If you add those BEGIN CERTIFICATE
and END CERTIFICATE
markers to your certificate it should work:
<?php
$data = // ... your certificate
// Add the missing PEM-enclosing
$x509Data =
"-----BEGIN CERTIFICATE-----\n"
. $data
. "\n-----END CERTIFICATE-----";
// this is the same but I've added "print_r" so it is nicely formated
$fp = fopen('cert.txt','w+');
fwrite($fp, 'data=>'.print_r(openssl_x509_parse($x509Data,true), true));
fclose($fp);
