Javascript JSEncrypt到PHP非对称加密

我尝试在客户端和服务器之间进行非对称加密，客户端使用公钥，服务器使用私钥

在客户端，我使用javascript中的JSEncrypt使用我的公钥进行加密。从那里，我使用AJAX将加密数据发送到我的PHP脚本。我尝试使用

openssl\u private\u decrypt（）

对数据进行解密，但它总是返回false。我试着告诉它期望不同的填充，即使我确信它是PKCS1

有人能告诉我我做错了什么吗

以下是所有相关代码：

JAVASCRIPT:

function getpubkey(){ //Gets Public Key from server
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function(){
    if (this.readyState == 4 && this.status == 200){
        pubkey = this.responseText;
    }
};
xmlhttp.open("POST", "PHP/ajax.php", false);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("do=getpub");
}


function encryptdata(plaintext){ //Encrypts argument with Public Key
var encrypt = new JSEncrypt();
encrypt.setPublicKey(pubkey);
var encrypted = encrypt.encrypt(plaintext);
return encrypted;
}


function login(){ //Sends login data to server and displays response on page
getpubkey();
var encuser = encryptdata(document.getElementById('username').value);
var encpass = encryptdata(document.getElementById('password').value);
encuser = window.btoa(encuser);
encpass = window.btoa(encpass);
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function(){
    if (this.readyState == 4 && this.status == 200){
            document.getElementById('maincontent').innerHTML = this.responseText;
    }
};
xmlhttp.open("POST", "PHP/ajax.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("do=login&param1="+encuser+"&param2="+encpass);

}

PHP（ajax.PHP）：

<?php

    header("Location: ../index.php");
    die();
}

您在哪里设置$priv？priv.php看起来像什么？$priv是所需priv.php文件中的一个变量。它只包含私钥，我发现由于格式问题，加密的数据没有及时到达php脚本。我使用base64编码/解码解决了这个问题。仍然不能正常工作。您加密的数据大小是多少？另外，如果这只是为了加密传输中的数据，只需使用HTTPS即可。数据大小不大。最多32字节。我可能最终只会使用HTTPS。然而，我仍然很想知道为什么这不起作用。
