从 c++ 移植代码到 c# - 使用 RSA PKCS#1 私钥加密

发布于 2024-11-05 17:51:05 字数 741 浏览 0 评论 0 原文

我正在尝试将这段代码从 c++ 移植到 c#：

...
strPrivateKey = "someBase64EncodedPrivateKey";
long sizeKey = DecodeBase64(strPrivateKey, pKey);
const unsigned char* _pKey = pKey;
d2i_RSAPrivateKey(&pRSA, &_pKey, sizeKey);
...

RSA_private_encrypt(sizeOfMessage, pMessage, pSignature, pRSA, RSA_PKCS1_PADDING);

...

到目前为止，这是我的代码：

var strPrivateKey = "someBase64EncodedPrivateKey";
var bytes = Convert.FromBase64String(strPrivateKey);

var rsa = new RSACryptoServiceProvider();

// How to set the private key to the rsa object?!

byte[] someDataToEncrypt = /* Set the data to encrypt */;
var encryptedData = rsa.Encrypt(someDataToEncrypt, false);

编辑：我不确定这是否是我应该参考的课程。

谢谢

I'm trying to port this piece of code from c++ to c#:

...
strPrivateKey = "someBase64EncodedPrivateKey";
long sizeKey = DecodeBase64(strPrivateKey, pKey);
const unsigned char* _pKey = pKey;
d2i_RSAPrivateKey(&pRSA, &_pKey, sizeKey);
...

RSA_private_encrypt(sizeOfMessage, pMessage, pSignature, pRSA, RSA_PKCS1_PADDING);

...

So far here is my code:

var strPrivateKey = "someBase64EncodedPrivateKey";
var bytes = Convert.FromBase64String(strPrivateKey);

var rsa = new RSACryptoServiceProvider();

// How to set the private key to the rsa object?!

byte[] someDataToEncrypt = /* Set the data to encrypt */;
var encryptedData = rsa.Encrypt(someDataToEncrypt, false);

EDIT:
I'm not ever sure if it's the class I should refer to.

Thanks

RSAParameters (http://msdn.microsoft.com/en-us/library/system.security.cryptography.rsaparameters.aspx) 可以使用 ImportParameters 方法。您可以在 RSAParameters 结构中对密钥进行编码。

通过添加来修复它：

At the begin of the private key: "-----BEGIN RSA PRIVATE KEY-----\r\n"
After each line of my private key : "\r\n"
At the end of my private key: "-----END RSA PRIVATE KEY-----"

最后，我使用 OpenSsl.NET 作为库。这篇文章最初解决了我的问题：
使用 OpenSSL.NET 和现有密钥解密 RSA

Fixed it by adding:

At the begin of the private key: "-----BEGIN RSA PRIVATE KEY-----\r\n"
After each line of my private key : "\r\n"
At the end of my private key: "-----END RSA PRIVATE KEY-----"

And finally, I used OpenSsl.NET as library. This post originally solved my problem:
Decrypting RSA using OpenSSL.NET with Existing Key
