PHP通过OpenSSL生成证书、密钥并且加密解密数据

关于PHP生成证书密钥,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。


    $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" =  '[email protected]' //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);
 
$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
