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);
- ?>
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
- ?>
