我的文本区域填充了使用上述公钥在RSA中加密的邮件。
加密的消息是：
oH1JVWIT7MOH4ObCjFlBuFcAUvooSZANMokFy5jApSi8n0ABVc9vwXP2EFl2x5 + UColU6s2VAU + RsZPV4ZgZu3 + GhN9pDUb1ZMVyYRECDy / 7h + mE + UdDZTPwP1TAcBrspL / XM6 + q6mJfUWbEKfR / 2vyNUhBxpt6QOhVaI29aHfU =
我的问题如下：我如何解密我的使用该公开密钥派生的私钥对的消息？有没有解密图书馆？
我的私钥是：

首先，我希望这不是您将在生产中使用的RSA私钥。
关于做在JavaScript端加密/解密，有各种各样的库，如 Standford的JSBN RSA加密库， ohdave.com的RSA在JavaScript实用程序中进行简单的加密/解密，但您对这些工具甚至您的体系结构的主要关注点是性能。我不会使用JavaScript进行RSA加密，除非是绝对必要的，没有其他的解决方法。
Hello I have this script that I set in Javascript :
<!DOCTYPE html>
<html lang="en">
<head>
<script src="jquery-1.7.2.min.js" type="text/javascript"></script>
<script language="JavaScript" type="text/javascript" src="jsbn.js"></script>

<script language="JavaScript">
function encryptData(){
var pem ="-----BEGIN PUBLIC KEY-----\

-----END PUBLIC KEY-----";
var key = RSA.getPublicKey(pem);
var message = "some text to RSA encrypt";
var encryptedMessage = RSA.encrypt(message, key);
$('#RSAMessageEncrypted').html(encryptedMessage);
}
</script>
</head>
<body onload=encryptData();>
<form>
<strong>RSA encrypted Message :</strong> <textarea rows="10" cols="100" id="RSAMessageEncrypted"></textarea><br>
</form>
</body>
</html>
My text area is filled with my message encrypted in RSA using the public key above.
The encrypted message is :
oH1JVWIT7MOH4ObCjFlBuFcAUvooSZANMokFy5jApSi8n0ABVc9vwXP2EFl2x5+UColU6s2VAU+RsZPV4ZgZu3+GhN9pDUb1ZMVyYRECDy/7h+mE+UdDZTPwP1TAcBrspL/XM6+q6mJfUWbEKfR/2vyNUhBxpt6QOhVaI29aHfU=
My question is as following: How can I decrypt my message using the private key pair that this public key was derived from? Is there any library for decryption?
My private key is :
-----BEGIN RSA PRIVATE KEY-----

First of all, I hope that's not the RSA private key that you are going to use in production.
As regards to doing the encryption/decryption on JavaScript side, there are various libraries such as Standford's JSBN RSA Encryption library and ohdave.com's RSA in JavaScript utility for doing simple encryption/decryption, but your main concern with these tools and even your architecture is performance. I would not do RSA encryption with JavaScript unless it was absolutely necessary and there were no other workarounds.
