Running into error on the 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
}
I used https://code.msdn.microsoft.com/vstudio/Pretty-Good-Privacy-using-4f473c67 as a reference.
I am confused about the parameters in the PgpEncryptionKeys.
Does anyone have a working example or help? this is my first time encrypting so i a little lost.

I'm using by this way:
I think can help you!
Helper:
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.");
}
Usage:
EncryptPgpFile(inputFile, outputFile, publicKeyPath, true, true);
