参考了别人的文章,自己做了笔记
①准备工作
找到php.ini 去掉openssl.dll前面的';'。
找到openssl.cnf的位置,我的在D:xamppapacheconf。
配置apache以支持SSL:打开apache的配置文件conf/httpd.conf
LoadModule ssl_module modules/mod_ssl.so、Include conf/extra/httpd-ssl.conf
去掉两行前面的#
注意修改httpd-ssl.conf 文件里的两个字段:
SSLCertificateFile "C:/Apache2.2/conf/server.crt"
SSLCertificateKeyFile "C:/Apache2.2/conf/server.key"
② 代码
<?php
$config = array(
"private_key_bits" => 1024, //字节数 512 1024 2048 4096 等
"private_key_type" => OPENSSL_KEYTYPE_RSA, //加密类型
"config" => "D:/xampp/apache/conf/openssl.cnf"
);
$privkeypass = '123456789'; //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
$dn = array(
"countryName" => "UK",
"stateOrProvinceName" => "Somerset",

// 生成公钥私钥资源
$res = openssl_pkey_new($config);
// 导出私钥 $priKey
openssl_pkey_export($res, $priKey,null,$config);
// 导出公钥 $pubKey
$pubKey = openssl_pkey_get_details($res);
$pubKey = $pubKey["key"];
//print_r($priKey); 私钥
//print_r($pubKey); 公钥
//直接测试私钥 公钥
$data = '直接测试成功!';
// 加密
openssl_public_encrypt($data, $encrypted, $pubKey);
// 解密
openssl_private_decrypt($encrypted, $decrypted, $priKey);
echo $decrypted;
//生成文件
$csr = openssl_csr_new($dn, $priKey,$config); //基于$dn生成新的 CSR (证书签名请求)
$sscert = openssl_csr_sign($csr, null, $priKey, 365,$config);//根据配置对证书进行签名
openssl_x509_export($sscert, $csrkey); //将公钥 证书存储到一个文件$sscert,由 PEM 编码格式命名。
openssl_pkcs12_export($sscert, $privatekey, $priKey, $privkeypass); //将私钥存储到名为的出 PKCS12 文件格式的字符串。 导出密钥$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);
// 测试私钥 秘钥
$privkeypass = '123456789'; //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
$data = "测试数据!"; //加密数据测试test
//私钥加密
openssl_pkcs12_read($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?'证书测试成功!':'证书测试失败!';; //输出验证结果,1:验证成功,0:验证失败
ps. 如果用txt编辑器建的密钥文件,记得去掉bom头
