(PHP 4 >= 4.2.0, PHP 5)

openssl_pkey_new — 新規に秘密鍵を生成する

説明

resource openssl_pkey_new ( [array $configargs] )

openssl_pkey_new() は、新しい秘密鍵と公開鍵の鍵ペアを作成します。鍵の公開部は、openssl_pkey_get_public() を使用して取得可能です。鍵の作成方法の詳細（ビット数など）を指定するには、configargs を使用します。 configargs の詳細な情報については openssl_csr_new() を参照ください。

注意: この関数を正しく機能させるには、有効な openssl.cnf がインストールされている必要があります。詳細な情報についてはインストールセクションの下にある注記を参照ください。

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.
