如何在C＃中对生成的RSA私钥进行加密和解密

Question

I have seen articles regarding encrypt/decrypt data using Private/Public key. All I want to do is to just encrypt a generated RSA private key already stored in a file. I have been browsing widely to get an idea how it can be done but with no luck.I presume my question is rather an unusual one. Please help!

Answer 1

First, you need a *Key derivation function, to turn your password into a symmetric key which you can use to encrypt your private key. If you solely use the .NET framework, you should use the Rfc2898DeriveBytes class for that. If you are able to use BouncyCastle, then SCrypt would be preferred.

Then you can encrypt your key, prefreably using the AES algorithm.
