For those interested in parsing the timestamps from the certificate, such as the valid to and valid from times, it should be noted that the format returned by this function is: YYMMDDHHMMSS This code snippet is useful for generating a unix timestamp for this purpose: <?php $fp = fopen("/path/to/cert.crt", "r"); $cert = fread($fp, 8192); fclose($fp); $data = openssl_x509_parse($cert); /** * Convert a timestamp from openssl_x509_parse to a unix timestamp * @param string $in openssl timestamp * @return integer unix timestamp */ function openssl_to_timestamp ($in) { $year = substr($in, 0, 2); /* NOTE: Yes, this returns a two digit year */ $month = substr($in, 2, 2); $day = substr($in, 4, 2); $hour = substr($in, 6, 2); $min = substr($in, 8, 2); $sec = substr($in, 10, 2); return gmmktime($hour, $min, $sec, $month, $day, $year); } var_dump(gmdate('r', openssl_to_timestamp($data['validTo']))); ?> This will output: string(31) "Fri, 29 Aug 2008 16:45:15 +0000" Compare this with the output of openssl x509 -in cert.crt -noout -text: Validity Not After : Aug 29 16:45:15 2008 GMT ---- Server IP: 64.71.164.2 Probable Submitter: 69.17.126.74 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.openssl-x509-read.php Edit -- https://master.php.net/note/edit/68796 Del: integrated -- https://master.php.net/note/delete/68796/integrated Del: useless -- https://master.php.net/note/delete/68796/useless Del: bad code -- https://master.php.net/note/delete/68796/bad+code Del: spam -- https://master.php.net/note/delete/68796/spam Del: non-english -- https://master.php.net/note/delete/68796/non-english Del: in docs -- https://master.php.net/note/delete/68796/in+docs Del: other reasons-- https://master.php.net/note/delete/68796 Reject -- https://master.php.net/note/reject/68796 Search -- https://master.php.net/manage/user-notes.php
