Need to encrypt a string and store it in aN XML File.

I store a users SMTP UserName and Password in a settings class, which is
serialized to an XML Settings File.

I need to encrypt the password string in some manner. Does anyone have any
ideas how to do that and still store it in the XML File?
I was thinking of putting the Encryption/Decryption code in the Get/Set
methods of the SMTPPassword Property.

Sample Code:

Public Sub Persist()
'// Save the Settings object to XML Files
Dim settingsPath As String =
IO.Path.Combine (Application.Us erAppDataPath, "settings.x ml")
Dim myXMLSerializer As Xml.Serializati on.XmlSerialize r
Dim settingsFile As IO.StreamWriter

'//Save the settings class
myXMLSerializer = New
Xml.Serializati on.XmlSerialize r(GetType(Setti ngs))
settingsFile = New IO.StreamWriter (settingsPath)
myXMLSerializer .Serialize(sett ingsFile, appSettings)
settingsFile.Cl ose()
End Sub

<Serializable() > Public Class Settings
Dim m_SMTPLoginName as String
Dim m_SMTPPassword as String
Public Property SMTPLoginName() as String
Return m_SMTPLoginName
End Get
Set(ByVal Value As String)
m_SMTPLoginName = Value
End Set
End Property
Public Property SMTPPassword() as String
Return m_SMTPPassword
End Get
Set(ByVal Value As String)
m_SMTPPassword = Value
End Set
End Property
End Class

After you run it through your encryption routine of choice (a two-way
routine, of course), just base-64 encode the results (see the System.Text
namespace for the Encoding class). Then you'll have normal text that you can
stick in the XML file.
