OAEP 与 SHA1 和 MGF1 与 BouncyCastle？

Question

我正在尝试RSA/ECB/OAEPWithSHA1AndMGF1Padding在 .NET Framework 2.0 上使用 BouncyCastle 来处理 c#。我得出这样的结论：IAsymmetricBlockCipher engine = new OaepEncoding(new RsaEngine(), new Sha1Digest(), new Sha1Digest(), null);using (var stream = new StreamReader(publicKey)){    var pemReader = new PemReader(stream);    var pemObj = pemReader.ReadObject();    var keyPair = (RsaKeyParameters)pemObj;    engine.Init(true, keyPair);}var message = "test";var data = Encoding.UTF8.GetBytes(message);var encrypted = engine.ProcessBlock(data, 0, data.Length);我的问题是，这是否相当于RSA/ECB/OAEPWithSHA1AndMGF1Padding使用 BouncyCastle 和 c# 或者什么是正确的方法？我对这里的参数也有疑问：IAsymmetricBlockCipher engine = new OaepEncoding(new RsaEngine(), new Sha1Digest(), new Sha1Digest(), null);我找不到将第二个定义Sha1Digest为 MGF1 之类的方法。

Answer 1

c = CipherUtilities.GetCipher("RSA/NONE/OAEPWithSHA1AndMGF1Padding");

c.Init(false, privKey);

outBytes = c.DoFinal(outBytes);

if (!AreEqual(outBytes, input))

{

    Fail("OAEP test failed on decrypt expected " + Hex.ToHexString(input) + " got " + Hex.ToHexString(outBytes));

}

注意 c 是一个 IBufferedCipher
