我有一个由RSACng类生成的公钥和私钥对。我可以将私钥持久保存到本地计算机->(程序数据->加密-> RSA->密钥)下的我的KSP(MicrosoftSoftwareKeyStorageProvider)中。但是,我无法持久保存由RSACng生成的公钥。如何将RSACng中的公钥持久保存到KSP(MicrosoftSoftwareKeyStorageProvider)?
我已经尝试使用CngKey保留公共密钥,但是这使我“不支持该操作”。请在下面的代码中查找。
public static void SaveKeyPairToKSP(KeyGenerationResult keyData, string keyName)
{
var myKSP = CngProvider.MicrosoftSoftwareKeyStorageProvider;
const bool MachineKey = true;
if (!CngKey.Exists(keyName, myKSP))
{
var keyParams = new CngKeyCreationParameters
{
ExportPolicy = CngExportPolicies.AllowArchiving,
KeyCreationOptions = (MachineKey) ? CngKeyCreationOptions.MachineKey : CngKeyCreationOptions.None,
Provider = myKSP
};
keyParams.Parameters.Add(new CngProperty("Length", BitConverter.GetBytes(keyData.KeySize), CngPropertyOptions.None));
keyParams.Parameters.Add(new CngProperty(CngKeyBlobFormat.GenericPrivateBlob.Format, keyData.PrivateBytes, CngPropertyOptions.Persist));
//Here is my public key that i want to store in my KSP
keyParams.Parameters.Add(new CngProperty(CngKeyBlobFormat.GenericPublicBlob.Format, keyData.PublicBytes, CngPropertyOptions.Persist));
CngKey.Create(CngAlgorithm.Rsa, keyName, keyParams);
}
}
