As you probably found, getting the public key is not as direct as you might think with this documentation. You can easily get into messages like: Warning: openssl_pkey_get_public(): Don't know how to get public key from this private key (the documentation lied) in D:\www\keys.php on line 4 The correct steps to get the whole thing seem to be these: <? $dn = array("countryName" => 'XX', "stateOrProvinceName" => 'State', "localityName" => 'SomewhereCity', "organizationName" => 'MySelf', "organizationalUnitName" => 'Whatever', "commonName" => 'mySelf', "emailAddress" => 'user@domain.com'); $privkeypass = '1234'; $numberofdays = 365; $privkey = openssl_pkey_new(); $csr = openssl_csr_new($dn, $privkey); $sscert = openssl_csr_sign($csr, null, $privkey, $numberofdays); openssl_x509_export($sscert, $publickey); openssl_pkey_export($privkey, $privatekey, $privkeypass); openssl_csr_export($csr, $csrStr); echo $privatekey; // Will hold the exported PriKey echo $publickey; // Will hold the exported PubKey echo $csrStr; // Will hold the exported Certificate ?> Now all you need to do is to make some research on each individual function.
