关于PHP生成证书密钥的资料真是好少啊，查了半天，最终还是在官方文档找到了相关资料，又根据自己的理解，整理成了以下代码，分成两部分：生成证书密钥、加密解密数据。直接复制下来做成两个文件运行就好啦。已经写了详细的注释，相信php程序员都能看得懂。

generate.php

$dn = array(
"countryName" => 'XX', //所在国家名称

"stateOrProvinceName" => 'State', //所在省份名称

"localityName" => 'SomewhereCity', //所在城市名称

"organizationName" => 'MySelf', //注册人姓名

"organizationalUnitName" => 'Whatever', //组织名称

"commonName" => 'mySelf', //公共名称

"emailAddress" => 'user@domain.com' //邮箱

);

$privkeypass = '111111'; //私钥密码

$numberofdays = 365; //有效时长

$cerpath = "./test.cer"; //生成证书路径

$pfxpath = "./test.pfx"; //密钥文件路径

//生成证书

$privkey = openssl_pkey_new();

$csr = openssl_csr_new($dn, $privkey);

$sscert = openssl_csr_sign($csr, null, $privkey, $numberofdays);

openssl_x509_export($sscert, $csrkey); //导出证书$csrkey

openssl_pkcs12_export($sscert, $privatekey, $privkey, $privkeypass); //导出密钥$privatekey

//生成证书文件

$fp = fopen($cerpath, "w");

fwrite($fp, $csrkey);

fclose($fp);

//生成密钥文件

$fp = fopen($pfxpath, "w");

fwrite($fp, $privatekey);

fclose($fp);

?>

复制代码

crypt.php

$privkeypass = '111111'; //私钥密码

$pfxpath = "./test.pfx"; //密钥文件路径

$priv_key = file_get_contents($pfxpath); //获取密钥文件内容

$data = "test"; //加密数据测试test

//私钥加密

openssl_pkcs12_read($priv_key, $certs, $privkeypass); //读取公钥、私钥

$prikeyid = $certs['pkey']; //私钥

openssl_sign($data, $signMsg, $prikeyid,OPENSSL_ALGO_SHA1); //注册生成加密信息

$signMsg = base64_encode($signMsg); //base64转码加密信息

//公钥解密

$unsignMsg=base64_decode($signMsg);//base64解码加密信息

openssl_pkcs12_read($priv_key, $certs, $privkeypass); //读取公钥、私钥

$pubkeyid = $certs['cert']; //公钥

$res = openssl_verify($data, $unsignMsg, $pubkeyid); //验证

echo $res; //输出验证结果，1：验证成功，0：验证失败

?>
