.Net 中的私钥加密
我正在寻找一种在 C# 中进行私钥加密的方法。
我以为我可以使用 RSACryptoServiceProvider，但它只支持公钥加密。
我在这个主题上发现的唯一的东西是这个项目，但我宁愿使用我可以在.net中找到的东西： http://www.codeproject.com/KB/security/PrivateEncryption.aspx
请注意，我不寻求签名。
请注意，我需要非对称加密。
有什么想法吗？
背景故事：
我正在将加密文件发送到正在运行应用程序的另一个系统。加密可确保文件不能被任何人更改（或多或少）或查看。应用程序能够使用公钥解密文件并对其执行某些操作。
我知道几乎任何人都可以从应用程序中获取公钥，在这种情况下这不是问题。
I am looking for a way to do private key encryption in C#.
I thought I could use the RSACryptoServiceProvider, but it only supports public key encryption.
The only thing I found on the subject was this project, but I would rather use something I can find in .net: http://www.codeproject.com/KB/security/PrivateEncryption.aspx
Please note I am not looking for signing.
Please note I require asymmetric encryption.
Any idea's?
Background story:
I am sending an encrypted file to another system which is running an application. The encryption is making sure the file cannot be altered (more or less) or viewed by anyone. The application is able to decrypt the file using the public key and do something with it.
I know pretty much anyone is able to get the public key from the application, this is not a problem in this case.

。公钥加密 - 当“按书本”完成时 - 将加密和签名分开（“不能更改”）。根据您的情况，请使用两对密钥，一对在应用程序内，一对在您的站点内。使用公共应用程序密钥加密该文件并使用您的私有密钥对该文件进行签名。
这是一个非常广泛的用法，我什至喜欢称其为“最佳实践”。至于否决票，我只能猜测排除在您的问题中签名会触发此操作。
Public Key Encryption - when done "by the book" - seperates encryption and signing ("cannot be altered"). In your case, use two key pairs, one within the application and one at your site. Encrypt the file using the public application key and sign the file using your private one.
This is a really widespread usage, I even like to call it "Best practice". As for the downvote, I can only guess that ruling out signing in your question triggered this.
不应该这样做。改为签名并使用对称加密。
It should not be done. Sign instead and use symmetric encryption.
