如何使用X509证书和C＃进行非对称加密？

Question

I am looking to encrypt files with X509 certificates using public and private keys and send them to a remote server. How would I do this? Is this even possible? How do I generate the certificate and then the public and private key pairs?

Answer 1

See this SO question how to create a RSACryptoServiceProvider from a X509Certificate2 that can be used to encrypt and decrypt files.

The .NET framework does not contain classes to generate X.509 certificates. Mono's security classes ( Mono.Security.X509 ) and BouncyCastle support the creation of X.509 certificates from C#. Alternatively, you can use tools like OpenSSL or makecert.exe to generate certificates.
