我如何将 RsaKeyParameters 发送到服务器，反之亦然？

Question

我在 Xamarin Forms 上使用 Bouncy Castle 进行非对称加密。但我正在研究客户端 <-> Web Api 结构。如何将 public 密钥发送到另一端？因为类型是 RsaKeyParameters .

RsaKeyPairGenerator rsaKeyPairGnr = new RsaKeyPairGenerator();
rsaKeyPairGnr.Init(new KeyGenerationParameters(new SecureRandom(), 512));
AsymmetricCipherKeyPair keyPair = rsaKeyPairGnr.GenerateKeyPair();
RsaKeyParameters publicKey = (RsaKeyParameters)keyPair.Public;

Answer 1

如果我有 RsaKeyParameters publicKey 并且需要将其发送到服务器，我可以使用以下方式进行转换：

//convert from key to string
SubjectPublicKeyInfo publicKeyInfo = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(publicKey);
byte[] serializedPublicBytes = publicKeyInfo.ToAsn1Object().GetDerEncoded();    
string serializedPublic = Convert.ToBase64String(serializedPublicBytes);
And then, i can convert the serializedPublic to RsaKeyParameters publicKey

//convert from string to key
RsaKeyParameters publicKey2 = (RsaKeyParameters)PublicKeyFactory.CreateKey(Convert.FromBase64String(serializedPublic));

但是有人可以告诉我通过 Http 库通过查询字符串传递 public 键是否是个好主意？

我如何将 RsaKeyParameters 发送到服务器，反之亦然？

How can i send a RsaKeyParameters to a server or vice versa?
