java - C# 中的 Java 椭圆曲线

问题描述

我在 Java 中得到了这个代码，我需要它在 C# 中。我尝试了 BouncyCastle，但不幸的是，我得到的只是奇怪的长键，它与 java 的键完全不同。任何人都可以帮忙吗？谢谢

ECParameterSpec spec = new ECParameterSpec(
        new EllipticCurve(
                new ECFieldFp(new BigInteger("115792089210356248762697446949407573530086143415290314195533631308867097853951")),
                new BigInteger("115792089210356248762697446949407573530086143415290314195533631308867097853948"),
                new BigInteger("41058363725152142129326129780047268409114441015993725554835256314039467401291")
        ),
        new ECPoint(

        1
);

KeyPairGenerator instance = KeyPairGenerator.getInstance("EC");
instance.initialize(spec);

KeyPair pair = instance.generateKeyPair();
String key64 = Base64.getEncoder().encodeToString(pair.getPublic().getEncoded());

System.out.println(key64);

我尝试过的 C# 代码：

SecureRandom random = new SecureRandom();

BigInteger order = new BigInteger("115792089210356248762697446949407573529996955224135760342422259061068512044369");

FpCurve curve = new FpCurve(
    new BigInteger("115792089210356248762697446949407573530086143415290314195533631308867097853951"),
    new BigInteger("115792089210356248762697446949407573530086143415290314195533631308867097853948"),
    new BigInteger("41058363725152142129326129780047268409114441015993725554835256314039467401291"),
    order,
    BigInteger.One
);

ECDomainParameters parameters = new ECDomainParameters(
    curve,
    curve.CreatePoint(
        new BigInteger("48439561293906451759052585252797914202762949526041747995844080717082404635286"),
        new BigInteger("36134250956749795798585127919587881956611106672985015071877198253568414405109")
    ),
    order,
    BigInteger.One
);

ECKeyPairGenerator pGen = new ECKeyPairGenerator();
ECKeyGenerationParameters genParam = new ECKeyGenerationParameters(parameters, random);
pGen.Init(genParam);

AsymmetricCipherKeyPair pair = pGen.GenerateKeyPair();
SubjectPublicKeyInfo pki = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(pair.Public);
string key64 = Convert.ToBase64String(pki.GetEncoded());

如您所见，C# 输出看起来不正确
