使用C＃中的Boncy Castel库基于密码生成RSA公共/私钥

Question

我想使用C＃中的Boncy Castel库加密使用密码的私钥生成一个RSA键对，然后将它们保存到分开文件，以便我可以在需要时使用它们来加密或解密事物

。能够生成RSA键盘并将其存储在单独的PEM文件中。我相信它是PKCS1格式，但我似乎无法弄清楚如何基于密码生成Keypair。

我在官方网站上查看了 https://www.bouncycastle.org/csharp t找到任何例子。 我还通过堆栈溢出一直搜索，没有成功。

至少我想出了如何使用密码生成RSA Keypair来对私钥进行加密，并使用AES-256-CBC与Bouncycastle C＃（1.9.2）一起加密钥匙
注意：两个密钥的均为PEM格式。
I got help from the following Link: https://csharp.hotexamples.com/site/file？

//Create Random
CryptoApiRandomGenerator randomGenerator = new CryptoApiRandomGenerator();

//RSAKeyPairGenerator generates the RSA keypair based on the random number and strength of the key required
RsaKeyPairGenerator rsaKeyPairGen = new RsaKeyPairGenerator();
rsaKeyPairGen.Init(new KeyGenerationParameters(new SecureRandom(randomGenerator), 2048));
AsymmetricCipherKeyPair keyPair = rsaKeyPairGen.GenerateKeyPair();

//Extracting the private key from the pair
RsaKeyParameters Privatekey = (RsaKeyParameters)keyPair.Private;

//Extracting the public key from the pair
RsaKeyParameters Publickey = (RsaKeyParameters)keyPair.Public;

//Creating public key in pem format\
TextWriter pubtxtWriter = new StringWriter();
PemWriter pubpemWriter = new PemWriter(pubtxtWriter);
pubpemWriter.WriteObject(Publickey);
pubpemWriter.Writer.Flush();
//now save the follwing string variable into a file. that's our public key
string print_publicKey = pubtxtWriter.ToString();

//encrypted Private Key
string password = "xxxxx";  //give desired password, with good strength
AsymmetricKeyParameter privateKey = keyPair.Private;
StringWriter sw = new StringWriter();
PemWriter pw = new PemWriter(sw);
pw.WriteObject(privateKey, "AES-256-CBC", password.ToCharArray(), new SecureRandom());
pw.Writer.Close();
pw.Writer.Flush();
//now save the follwing string variable into a file. that's our "Encrypted private key"
string encprvKey = sw.ToString();
