Trying to use PGPBlackBox to encrypt with a supplier's public key and sign with our secret key...can't seem to get it working ... any help appreciated...

Public Sub SignAndEncryptToken()
Dim encryptionKey As New TElPGPKeyring
Dim signingKey As New TElPGPKeyring

Dim pgpWriter As New TElPGPWriter

Dim publicKey As New TElPGPPublicKey
Dim secretKey As New TElPGPSecretKey
Dim token As String
Dim userName As String

userName = Users.UserController.GetCurrentUserInfo.Username
pgpWriter.EncryptionType = SBPGP.TSBPGPEncryptionType.etBoth
SBUtils.Unit.SetLicenseKey("licencekey here")


signingKey.SecretKeys(0).Passphrase = "ibmfit323"
pgpWriter.Armor = True
pgpWriter.ArmorHeaders.Add("Version: EldoS PGPBlackbox (.NET edition)")
pgpWriter.ArmorBoundary = "PGP MESSAGE"

pgpWriter.EncryptingKeys = encryptionKey
pgpWriter.SigningKeys = signingKey
pgpWriter.EncryptionType = TSBPGPEncryptionType.etBoth

pgpWriter.Passphrases.Text = "xxxeeeddd"

pgpWriter.InputIsText = True

token = DateTime.UtcNow + "," + "TestUser"
Dim memStream As New MemoryStream
Dim outStream As System.IO.FileStream
outStream = New System.IO.FileStream("c:\temp\encryptedtoken.txt", FileMode.Create)

Dim data() As Byte = Encoding.Unicode.GetBytes(token)

memStream.Write(data, 0, data.Length)

pgpWriter.EncryptAndSign(memStream, outStream, 0)

pgptoken.Value = outStream.ToString()

End Sub
Private Sub pgpWriter_OnKeyPassphrase(ByVal Sender As Object, ByVal key As SBPGPKeys.TElPGPCustomSecretKey, ByRef Passphrase As String, ByRef Cancel As Boolean) Handles pgpWriter.OnKeyPassphrase
Dim pass As String

pass = "xxxeeeddd"
Passphrase = pass
End Sub

What is your exact problem? Do you get an error or no output or what?

Does the sample application work?

Sincerely yours

It works, but the supplier claims it is not encrypted with their public key.

Your code seems to be correct at first glance. Would you be so kind to provide us the public key of your supplier so that we could try to reproduce the issue in our conditions? There won't be any security risk, since the key is public and [in general case] can be given to everyone. You can use either the helpdesk system (http://www.eldos.com/support/ticket_list.php) or support@eldos.com address to send us the key.

BTW, are you using the latest build of SecureBlackbox?

Sure. Actually, we plan to publish a new build update later today, so first of all I suggest you to upgrade to it when it is available and check if the problem still exists.
