php生成加密公钥加密私钥实例详解
生成公钥私钥 win下必须要openssl.cof支持 liunx一般已自带安装
$config=array(
//"digest_alg"=>"sha512",
"private_key_bits"=>512,//字节数512102420484096等
"private_key_type"=>OPENSSL_KEYTYPE_RSA,//加密类型
);
//1.创建公钥和私钥返回资源
$res=openssl_pkey_new($config);
//从得到的资源中获取私钥并把私钥赋给$privKey
openssl_pkey_export($res,$privKey);
//从得到的资源中获取私钥并把私钥赋给$pubKey
$pubKey=openssl_pkey_get_details($res);
$pubKey=$pubKey["key"];
var_dump(array('privKey'=>$privKey,'pubKey'=>$pubKey));
die;
//2.加密解密数据要加密的数据
$data='plaintextdatagoeshere';
//对$data进行加密要加密的数据字符串得到加密后的数据加密所需要的公钥
openssl_public_encrypt($data,$encrypted,$pubKey);
echobase64_encode($encrypted);
//对加密后的数据进行解密解密的数据得到解密后的数据解密所需要的私钥
$decrypted=base64_decode($encrypted);
openssl_private_decrypt($encrypted,$decrypted,$privKey);
echo$decrypted;
//3.一个加密解密类
classrsa{
private$public_key='';//公密钥
private$private_key='';//私密钥
private$public_key_resource='';//公密钥资源
private$private_key_resource='';//私密钥资源
