如何在我的.NET应用程序中使用Win32 CryptoAPI生成的密钥blob？

[StructLayout(LayoutKind.Sequential)]
public struct PUBLICKEYBLOB
{
    public byte bType;
    public byte bVersion;
    public short reserved;
    public ALG_ID aiKeyAlg;
    public byte[] PublicKey;
}

public static RSAParameters ConvertPublicKeyToRSAParameters(byte[] publicKeyBlob)
{
    GCHandle handle = GCHandle.Alloc(publicKeyBlob, GCHandleType.Pinned);
    PUBLICKEYBLOB publicKey = (PUBLICKEYBLOB)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(PUBLICKEYBLOB));
    handle.Free();

    RSAParameters parameters = new RSAParameters();
    parameters.Modulus = publicKey.PublicKey[0..(publicKey.PublicKey.Length / 2)];
    parameters.Exponent = publicKey.PublicKey[(publicKey.PublicKey.Length / 2)..];

    return parameters;
}

byte[] publicKeyBlob = GetPublicKeyBlobFromCryptoAPI();
RSAParameters parameters = ConvertPublicKeyToRSAParameters(publicKeyBlob);

using RSA rsa = RSA.Create();
rsa.ImportParameters(parameters);

byte[] dataToEncrypt = Encoding.UTF8.GetBytes("Hello, world!");
byte[] encryptedData = rsa.Encrypt(dataToEncrypt, RSAEncryptionPadding.OaepSHA256);

byte[] signatureToVerify = GetSignatureToVerify();
byte[] dataToVerify = Encoding.UTF8.GetBytes("Hello, world!");
bool isVerified = rsa.VerifyData(dataToVerify, signatureToVerify, HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1);
