[dev-crypto-csharp] ASCII armored PGP output

[Alex Malmyguine]

Can anyone please explain the correct way to produce ASCII armored PGP 
encrypted output?
Using below code, I produce binary encrypted files, and I can decrypt them. But 
if ASCIIArmor == true, that produced what looked like a partial output, which I 
could not decrypt. Am I applying ArmoredOutputStream() to a wrong stream?


            static Stream ChainEncryptedOut(Stream outputStream)
            {
                PgpEncryptedDataGenerator encryptedDataGenerator = new 
PgpEncryptedDataGenerator(SymmetricKeyAlgorithmTag.TripleDes, new 
SecureRandom());
                encryptedDataGenerator.AddMethod(EncryptionKey);
                return encryptedDataGenerator.Open(ASCIIArmor ? new 
ArmoredOutputStream(outputStream) : outputStream, new byte[BufferSize]);
            }

            static Stream ChainLiteralOut(Stream encryptedOut, FileInfo file, 
long length)
            {
                return new PgpLiteralDataGenerator().Open(encryptedOut, 
PgpLiteralData.Binary, file == null ? "" : file.Name, length, DateTime.Now);
            }

Calling code:

                using (Stream encryptedOut = ChainEncryptedOut(outputStream))
                {
                    using (Stream literalOut = ChainLiteralOut(encryptedOut, 
unencryptedFileInfo, inputStream.Length))
                    {
                        WriteOutput(literalOut, inputStream);
                    }
                }

When encrypting “Hello World”, the binary output is 575 bytes long, and the 
ASCII armored output is 844 bytes long, looking as follows:

Should there be more output? Should it be closed with something like “----END 
PGP MESSAGE----“?

Thank you!
