.net核心PGP加密解密

Question

运行进入错误就void Encryption().

public void Encryption()
{
    #region PGP Encryption 

    PgpEncryptionKeys encryptionKeys = new PgpEncryptionKeys(@"C:\Keys\PGPPublicKey.asc", @"C:\Keys\PGPPrivateKey.asc", "password");
    PgpEncrypt encrypter = new PgpEncrypt(encryptionKeys);
    using (Stream outputStream = File.Create("C:\Keys\EncryptData.txt"))
    {
        encrypter.EncryptAndSign(outputStream, new FileInfo(@"D:\Keys\PlainText.txt"));
    }
    Console.WriteLine("Encryption Done !");

    #endregion
}

我用过https://code.msdn.microsoft.com/vstudio/Pretty-Good-Privacy-using-4f473c67 作为参考。

我对 PgpEncryptionKeys 中的参数感到困惑。

有人有工作示例或帮助吗？这是我第一次加密，所以我有点迷路。

我是这样使用的：

我觉得可以帮到你！

帮手：

public static void EncryptPgpFile(string inputFile, string outputFile, string publicKeyFile, bool armor, bool withIntegrityCheck)
{
    using (Stream publicKeyStream = File.OpenRead(publicKeyFile))
    {
        PgpPublicKey pubKey = ReadPublicKey(publicKeyStream);

        using (MemoryStream outputBytes = new MemoryStream())
        {
            PgpCompressedDataGenerator dataCompressor = new PgpCompressedDataGenerator(CompressionAlgorithmTag.Zip);
            PgpUtilities.WriteFileToLiteralData(dataCompressor.Open(outputBytes), PgpLiteralData.Binary, new FileInfo(inputFile));

            dataCompressor.Close();
            PgpEncryptedDataGenerator dataGenerator = new PgpEncryptedDataGenerator(SymmetricKeyAlgorithmTag.Cast5, withIntegrityCheck, new SecureRandom());

            dataGenerator.AddMethod(pubKey);
            byte[] dataBytes = outputBytes.ToArray();

            using (Stream outputStream = File.Create(outputFile))
            {
                if (armor)
                {
                    using (ArmoredOutputStream armoredStream = new ArmoredOutputStream(outputStream))                   
                    using (Stream outputStream = dataGenerator.Open(armoredStream, dataBytes.Length))
                        outputStream.Write(dataBytes, 0, dataBytes.Length);
                }
                else
                {
                    using (Stream outputStream = dataGenerator.Open(armoredStream, dataBytes.Length))
                        outputStream.Write(dataBytes, 0, dataBytes.Length);
                }
            }
        }
    }
}

private static PgpPublicKey ReadPublicKey(Stream inputStream)
{
    inputStream = PgpUtilities.GetDecoderStream(inputStream);
    PgpPublicKeyRingBundle pgpPub = new PgpPublicKeyRingBundle(inputStream);

    foreach (PgpPublicKeyRing keyRing in pgpPub.GetKeyRings())
    {
        foreach (PgpPublicKey key in keyRing.GetPublicKeys())
        {
            if (key.IsEncryptionKey)
                return key;
        }
    }

    throw new ArgumentException("Can't find encryption key in key ring.");
}

用法：

EncryptPgpFile(inputFile, outputFile, publicKeyPath, true, true);
