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
<?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
<?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 ?>
