Ive seen a couple of threads on this for Java about closing the stream. I just don't understand what they are getting at though. I will convert everything to usings again once i get the issue figured out.

Is it possible that its because I'm storing the Private Key as a string then converting it?

        public static MemoryStream StringToStream(string toConvert)

    {

        // convert string to stream

        var byteArray = Encoding.Default.GetBytes(toConvert);

        //byte byteArray = Encoding.ASCII.GetBytes(contents);

        var stream = new MemoryStream(byteArray);



        return stream;

    }

I have intentions of enhancing this a bit but when i couldnt get it working I went back to basically the version posted here Original Post

public static byte DecryptBytes(byte inputData)

    {

        if(!PrivateKeyPopulated)

        { throw new Exception("PrivateKey Must be populated!!!");}



        if (String.IsNullOrWhiteSpace(_passcode))

        { throw new Exception("Passcode Must be populated!!!"); }



        byte error = Encoding.ASCII.GetBytes("ERROR");



        Stream inputStream = new MemoryStream(inputData);

        inputStream = PgpUtilities.GetDecoderStream(inputStream);

        MemoryStream decoded = new MemoryStream();



        try

        {

            PgpObjectFactory pgpF = new PgpObjectFactory(inputStream);

            PgpEncryptedDataList enc;

            PgpObject o = pgpF.NextPgpObject();



            //

            // the first object might be a PGP marker packet.

            //

            if (o is PgpEncryptedDataList)

                enc = (PgpEncryptedDataList)o;

            else

                enc = (PgpEncryptedDataList)pgpF.NextPgpObject();



            //

            // find the secret key

            //

            PgpPrivateKey sKey = null;

            PgpPublicKeyEncryptedData pbe = null;

            PgpSecretKeyRingBundle pgpSec = new PgpSecretKeyRingBundle(

            PgpUtilities.GetDecoderStream(PSS_PGPEncrypt.StringToStream(_privateKey)));

            foreach (PgpPublicKeyEncryptedData pked in enc.GetEncryptedDataObjects())

            {

                sKey = FindSecretKey(pgpSec, pked.KeyId, _passcode.ToCharArray());

                if (sKey != null)

                {

                    pbe = pked;

                    break;

                }

            }

            if (sKey == null)

                throw new ArgumentException("secret key for message not found.");



            Stream clear = pbe.GetDataStream(sKey);<------ KABOOOM

            PgpObjectFactory plainFact = new PgpObjectFactory(clear);

            PgpObject message = plainFact.NextPgpObject();



            if (message is PgpCompressedData)

            {

                PgpCompressedData cData = (PgpCompressedData)message;

                PgpObjectFactory pgpFact = new PgpObjectFactory(cData.GetDataStream());

                message = pgpFact.NextPgpObject();

            }

                PgpLiteralData ld = (PgpLiteralData)message;

                Stream unc = ld.GetInputStream();

                Streams.PipeAll(unc, decoded);

            }

            else if (message is PgpOnePassSignatureList)

                throw new PgpException("encrypted message contains a signed message - not literal data.");

            else

                throw new PgpException("message is not a simple encrypted file - type unknown.");



            if (pbe.IsIntegrityProtected())

            {

                if (!pbe.Verify())

                     throw new Exception("PGP Error - Message failed integrity check.");

                //else

                    //"Message integrity check passed.", "PGP Error"

            }

            else

            {

                //MessageBox.Show(null, "No message integrity check.", "PGP Error", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }



            return decoded.ToArray();
