进口大众/在BouncyCastle的私有密钥ECDH

Question

我试图导入BouncyCastle的公共和私有密钥ECDH。要导入公钥我使用C＃代码波纹管和代码是正常工作：

byte[] pc = HexStringToByteArray(PUBLIC_KEY);
var ecdp = TlsEccUtilities.GetParametersForNamedCurve(NamedCurve.secp256r1);
var basePoint = TlsEccUtilities.ValidateECPublicKey(TlsEccUtilities.DeserializeECPublicKey(null, ecdp, pc));
SubjectPublicKeyInfo subinfo = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(basePoint);
ECPublicKeyParameters publicKey = (ECPublicKeyParameters)PublicKeyFactory.CreateKey(subinfo);

公钥：042e3e5ccf6b9ab04be7a22f3faccfde73c87e87155394a34815408a896ca18a374dac669af3bf6220fc863767f4af47507c5bc221fc4a19874daf39b4074e3eb8

私钥：be3f9bff87973356d04dad279e21535925c3656db011c9ae76b5a7f09ef8d9de

但我无法找到一个解决方案来导入私有密钥。能否请你帮我这个问题？

芬利我找到了解决办法：

// Import public key
byte[] pc = HexStringToByteArray(PUBLIC_KEY);
var ecdp = TlsEccUtilities.GetParametersForNamedCurve(NamedCurve.secp256r1);
var basePoint = TlsEccUtilities.ValidateECPublicKey(TlsEccUtilities.DeserializeECPublicKey(null, ecdp, pc));
SubjectPublicKeyInfo subinfo = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(basePoint);
ECPublicKeyParameters publicKey = (ECPublicKeyParameters)PublicKeyFactory.CreateKey(subinfo);

// Import private key
BigInteger bi = new BigInteger(HexStringToByteArray(PRIVATE_KEY));
ECPrivateKeyParameters privateKey = new ECPrivateKeyParameters(bi, publicKey.Parameters);
