注意: 必須安裝有效的 openssl.cnf 以保證此函數(shù)正確運(yùn)行。參考有關(guān)安裝的說明以獲得更多信息。
csr
由openssl_csr_new()函數(shù)生成的CSR. 也可以是由類似file://path/to/csr格式指定的指向PEM編碼的CSR路徑,或者是一個(gè)由openssl_csr_export()函數(shù)生成的字符串。
cacert
生成的證書將由cacert
簽名。
如果cacert
為 null
, 生成的證書將是自簽名證書。
priv_key
priv_key
是cacert
證書對(duì)應(yīng)的私鑰。
days
days
指定生成的證書在幾天內(nèi)有效的時(shí)間長(zhǎng)度。
configargs
你可以通過configargs
確定CSR簽名。
查看openssl_csr_new() 方法獲取
configargs
的更多相關(guān)信息。
serial
可選的發(fā)行證書編號(hào)。如果沒有指定默認(rèn)值為0.
示例 #1 openssl_csr_sign() example - signing a CSR (how to implement your own CA)
<?php
// Let's assume that this script is set to receive a CSR that has
// been pasted into a textarea from another page
$csrdata = $_POST["CSR"];
// We will sign the request using our own "certificate authority"
// certificate. You can use any certificate to sign another, but
// the process is worthless unless the signing certificate is trusted
// by the software/users that will deal with the newly signed certificate
// We need our CA cert and its private key
$cacert = "file://path/to/ca.crt";
$privkey = array("file://path/to/ca.key", "your_ca_key_passphrase");
$usercert = openssl_csr_sign($csrdata, $cacert, $privkey, 365, array('digest_alg'=>'sha256') );
// Now display the generated certificate so that the user can
// copy and paste it into their local configuration (such as a file
// to hold the certificate for their SSL server)
openssl_x509_export($usercert, $certout);
echo $certout;
// Show any errors that occurred here
while (($e = openssl_error_string()) !== false) {
echo $e . "\n";
}
