PHP openssl_pkcs12_read() Function Last Updated : 23 Sep, 2020 Comments Improve Suggest changes Like Article Like Report The openssl_pkcs12_read() function is a built-in function in PHP and is used by the PKCS # 12 certificate store to convert it into an array provided by pkcs12. A PKCS #12 file may be encrypted and signed. Syntax: bool openssl_pkcs12_read( string $pkcs12, array &$certs, string $pass ) Parameters: This function accepts three parameters as mentioned above and described below: $pkcs12: PKCS #12 is one of the family of standards called Public-Key Cryptography Standards (PKCS) published by RSA Laboratories. $certs: If successful, this will contain the Certificate Store Information.$pass: This parameter is used for the encryption password for unlocking the PKCS#12 file. Return Values: This function returns TRUE on success or FALSE on failure. Example: PHP <?php $dn = array( "countryName" => 'xx', "stateOrProvinceName" => 'uttar prradesh', "localityName" => 'varanasi', "organizationName" => 'geeksforgeeks', "organizationalUnitName" => 'geeks team', "commonName" => 'people', "emailAddress" => '[email protected]' ); $privateKeyPass = 'dummyPassword'; $numberOfDays = 108; $privateKey = openssl_pkey_new(); $csr = openssl_csr_new($dn, $privateKey); // Create a csr file, change null to // a filename to save $sscert = openssl_csr_sign($csr, null, $privateKey, $numberOfDays); // On success $publicKey will hold // the PEM content openssl_x509_export($sscert, $publicKey); // Export the privateKey as a PEM content openssl_pkey_export($privateKey, $privateKey, $privateKeyPass); // Parses the $privateKey and used by // openssl_pkcs12_export_to_file. $key = openssl_pkey_get_private( $privateKey, $privateKeyPass); $certificateOutput = null; // Save the pfx file to $certificateOutput openssl_pkcs12_export($sscert, $certificateOutput, $key, $privateKeyPass); // openssl_pkcs12_read reads the pkcs12 // certificate and store into array openssl_pkcs12_read ($certificateOutput, $readableOutput, $privateKeyPass ); var_dump($readableOutput); ?> Output: array(2) { ["cert"]=> string(1444) "-----BEGIN CERTIFICATE----- MIID/DCCAuSgAwIBAgIBADANBgkqhkiG9w0BAQUFADCBljELMAkGA1UEBhMCeHgx FzAVBgNVBAgMDnV0dGFyIHBycmFkZXNoMREwDwYDVQQHDAh2YXJhbmFzaTEWMBQG A1UECgwNZ2Vla3Nmb3JnZWVrczETMBEGA1UECwwKZ2Vla3MgdGVhbTEPMA0GA1UE AwwGcGVvcGxlMR0wGwYJKoZIhvcNAQkBFg51c2VyQGdlZWtzLmNvbTAeFw0yMDA5 MDExNjI3MDBaFw0yMDEyMTgxNjI3MDBaMIGWMQswCQYDVQQGEwJ4eDEXMBUGA1UE CAwOdXR0YXIgcHJyYWRlc2gxETAPBgNVBAcMCHZhcmFuYXNpMRYwFAYDVQQKDA1n ZWVrc2ZvcmdlZWtzMRMwEQYDVQQLDApnZWVrcyB0ZWFtMQ8wDQYDVQQDDAZwZW9w bGUxHTAbBgkqhkiG9w0BCQEWDnVzZXJAZ2Vla3MuY29tMIIBIjANBgkqhkiG9w0B AQEFAAOCAQ8AMIIBCgKCAQEAxDzM5/lUYUir/5Q42Dh1XJk+V9jZm+CQ2QTD9LHY +AntTX7jxPMdndXm/igd0IEgV0jVEOh+Y/ErlJEJJjMBFCMzbkL+goP15yqwxDEb OoMEdCJ9StJywc4x/SbgIZLK6cHjqsUgzNIcUdjYjZ/BqN+C/9sXO0v3ArBsmOB3 AgycPxda0PoPcFy2oNMyM7FnJXnPvglJfozdBricggi0hUkMYih2fPWEpNS2dEgf DmwpiXYu3S4gV0p0l08Q9VFdls8M2X9Nxp4dWV0lfWC8HkmmPOZofMipTsQ0Qvix /TuA/xxg9ozRdOLv5JOwD8GJctFGKXkXstGPC4Z5+kwBMwIDAQABo1MwUTAdBgNV HQ4EFgQUVEplgv0Z9eK8NE1YkVBJ0WuNFZwwHwYDVR0jBBgwFoAUVEplgv0Z9eK8 NE1YkVBJ0WuNFZwwDwYDVR0TAQH/BAUwAwEB/zANBgkqhkiG9w0BAQUFAAOCAQEA EcAu+9VKra4U32LLwHcX+80+LFwwwpzdehFEscfiBxr9zwCbszj1R75gL8AsGhjo 8OKE26+uTABjkElV7NJu9hgeDHxy9/an3xlz+MsEcoaFv9N9qCgqjX/Ihbwv7AHw N8VxtVrhjyY6ScwyvOaR9Zo8tHNY04tGxqAfRLX5X2TN2EvzpijoLZMOIgsHqQFB MocshV2BEJ/teom+CactKvrSHcQPwhRpE2dnEqsWK9vai4k1byHpTIAQdb3B+Ytz MIOMd2wWuWr5EXwoUIaf8pzKAIEQjxNF+yUIMNkXNhaN3NxGIDrWh9057zjYHR2I yxFL/nK5hEIEWiCyUtd1nQ== -----END CERTIFICATE----- " ["pkey"]=> string(1704) "-----BEGIN PRIVATE KEY----- MIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwggSjAgEAAoIBAQDEPMzn+VRhSKv/ lDjYOHVcmT5X2Nmb4JDZBMP0sdj4Ce1NfuPE8x2d1eb+KB3QgSBXSNUQ6H5j8SuU kQkmMwEUIzNuQv6Cg/XnKrDEMRs6gwR0In1K0nLBzjH9JuAhksrpweOqxSDM0hxR 2NiNn8Go34L/2xc7S/cCsGyY4HcCDJw/F1rQ+g9wXLag0zIzsWclec++CUl+jN0G uJyCCLSFSQxiKHZ89YSk1LZ0SB8ObCmJdi7dLiBXSnSXTxD1UV2WzwzZf03Gnh1Z XSV9YLweSaY85mh8yKlOxDRC+LH9O4D/HGD2jNF04u/kk7APwYly0UYpeRey0Y8L hnn6TAEzAgMBAAECggEAFLJU6iJhw+DmQw5e8G8D8cA30wwL52TH4huejzAysfZa ENJRM3RwqzTkJ+oTOupjftEvp5jdu6yz6/df/6dhdb5ArmBid2Fzje3ytr53ILSw w47fqASKFeapXwm6mc/hlsXcPSaNTwzZ78fvDwDKbAUmy9VPnfFlG+N/kKAb7Rs3 8BUVmeAAhQ0ggRFDjzyK/sNIzK1iJO9xqpWemiWMqiYIvOzPxGymx0O4M9y8k5wo lAgezRcoYUB4zQsWqkj5X/5NEZsEjy4/jYy/KpCz7LaIPIoZpTqIA0HOetspafuI P+l4N1vU14wMXeQ0oZCKiysAIExmtMfHmyF7uzbIAQKBgQDzHtOkD8aDcSNOg4Qp Q/SupcSSQZ93k4xVc3OjRPbBc8OIG+T7gwOS+Y6PpUAbYV7QKtVRNZ0W75qiafRk akA1Y2CuG24lCE3u7qyUSx/zE9ehUg0MDXcNkauSYfD+1BbIlyQSRaZhGYiKJ5f3 jJuTqS3W4zkPvxLKc2cSGJb1RQKBgQDOoicPFut1SpIW/wVhzoxXfM8IvyW3KlnE PaqPLFLh5PomiQVhcvd0fKm6FV3sjVI7I++TYzKcpix8V+B2axSTuHrsYCNNGz8L BE7pOMbEZVE+SPwYT8G15QdiAKxITbNz1YkxB9yBarpAoRw4THAtpnhZhclAzBj5 0dwwTN+YFwKBgQCWXDZgfTE1Eb/YSxZtvw2RBgywt808UxCzuJeIHprNwh7oCvhv ZPPM7nLw/C7NwEa3UAZmF1Z0XPOyBv2TLPNREYk1pNlWJfCtGQe7H0s/NsJhjzFq htlelv0Zp2E4+Uqt/GvesRzZaMU9TId8HoYJqNQk1prv1ih09TKFypdyUQKBgHbT CnED9hz55+6vcjHfbBb3X7sg6JhfE0XlTEqO646ZdTxpuR1j1mc3NQccOGnKjsoR jTiNZ9JrQNO0WRDf3PJhuNZrJoG1tFgqfxJgovTXapPNtqJoYvWtocQ6rNfbTuHC nuUCJ0yIylhWDXtWgX/O5hBc/fF0LLykcOGZo067AoGACL/iSs8wNse15sEJ1OdT SNgL4AnwzyP/wnyIEN57GVhJV9XJCuhlUDhQhn1dRVKmsi3pWMlPldZYgdiZGH6y 9p12cXSJywVIdwszld3OpXhFS+TwMTbAm49qHtvP2TovsPJpEHLXDBEZBo7k1oHU Uu3UyCB/z8dWkOINHWoi5/0= -----END PRIVATE KEY----- " } Comment More infoAdvertise with us Next Article PHP Syntax S shubham_singh Follow Improve Article Tags : Web Technologies PHP PHP-function Similar Reads PHP Tutorial PHP is a popular, open-source scripting language mainly used in web development.
