生成密钥对使用充气城堡

Question

我有生成密钥对使用BC如下Java代码：

KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); 
     keyGen.initialize(1024); 
     KeyPair key = keyGen.generateKeyPair(); 
     PrivateKey priv = key.getPrivate(); 
     PublicKey pub = key.getPublic(); 
     String privateKey = new String(Base64.encode(priv.getEncoded(), 0,priv.getEncoded().length, Base64.NO_WRAP)); 
     String publicKey1 = new String(Base64.encode(pub.getEncoded(), 0,pub.getEncoded().length, Base64.NO_WRAP)); 
     String publicKey = new String(Base64.encode(publicKey1.getBytes(),0, publicKey1.getBytes().length, Base64.NO_WRAP)); 

现在我想用BC在C＃中做的一样。我通过nuget包管理器下载了WP8BouncyCastle库。我已经写为：

var kpgen = new RsaKeyPairGenerator(); 

      kpgen.Init(new KeyGenerationParameters(new SecureRandom(new CryptoApiRandomGenerator()), 1024)); 

      var keyPair = kpgen.GenerateKeyPair(); 
      AsymmetricKeyParameter privateKey = keyPair.Private; 
      AsymmetricKeyParameter publicKey = keyPair.Public; 


      string prvKey = Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(privateKey.ToString())); 
      string pubKey = Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(publicKey.ToString())); 
      string pubKey1 = Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(pubKey.ToString())); 

但我需要在Java中可用getEncoded()方法，它是不是在C＃BC库可用。这个getEncoded()方法用于将给定的密钥转换为X.509编码密钥。在Java的情况下，公开密钥获得两次转换（getencoded()和getBytes()），我无法在C＃中执行相同的操作。

有没有解决方法？

使用私钥以下代码：

PrivateKeyInfo pkInfo = PrivateKeyInfoFactory.CreatePrivateKeyInfo(keyPair.Private); 
String privateKey = Convert.ToBase64String(pkInfo.GetDerEncoded()); 

，并按照公众：

SubjectPublicKeyInfo info = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(keyPair.Public); 
String publicKey = Convert.ToBase64String(info.GetDerEncoded());
