C＃ - AsymmetricCipherKeyPair为十六进制

Question

我想要一个以十六进制格式生成的ECDSA AsymmetricCipherKeyPair。公钥和私钥。

现在我这样做：

//Generate key pair
ECKeyPairGenerator gen = new ECKeyPairGenerator("ECDSA");
SecureRandom secureRandom = new SecureRandom();
KeyGenerationParameters keyGenParam = new KeyGenerationParameters(secureRandom, keySize);
gen.Init(keyGenParam);
AsymmetricCipherKeyPair keys = gen.GenerateKeyPair();

//Create a PEM and then extract the BASE64 part
var key = keys.Private;
TextWriter textWriter = new StringWriter();
PemWriter pemWriter = new PemWriter(textWriter);
pemWriter.WriteObject(key);
pemWriter.Writer.Flush();
string pem = textWriter.ToString();
var pem2 = pem.Split('\r').Skip(1).TakeWhile(i => !i.Contains("-----")).ToArray();
pem = string.Join("",pem2);

//BASE64 to byte[] to hex
byte[] bytes = Convert.FromBase64String(pem);
string hex = BitConverter.ToString(bytes);

必须有一种更简单的方法来获得十六进制输出。

Answer 1

对于私钥：

bytes = Org.BouncyCastle.Pkcs.PrivateKeyInfoFactory.CreatePrivateKeyInfo(keys.Private).ParsePrivateKey().GetDerEncoded();

和公众：

bytes = Org.BouncyCastle.X509.SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(keys.Public).GetDerEncoded();
