COMO ASSINAR UM ARQUIVO DIGITALMENTE

Bom dia,

pessoal estou com uma dúvida. Possuo um sistema de jobs (similar ao tasks do windows) porém esses jobs são criados a partir do meu sistema.

Funciona assim:

eu crio uma DLL com a [Ô]funcionalidade[Ô] e implemento a interface IJob que eu criei. Depois desse processo eu gero um XML com as configurações. (nome do job, tipo, intervalo, horario de inicio e etc...). No terceiro momento eu entro no meu sistema e acesso a tela de criação de jobs, nesta tela eu seleciona o XML e a DLL e o sistema [Ô]une[Ô] os 2 criando um arquivo com a extensão .JOB.

Isso tudo funciona perfeitamente bem, o problema é que eu QUERO assinar esses arquivos .job digitalmente com um certificado para que o sistema não rode um [Ô]Job[Ô] que não passou pelo processo de validação e homologação.

Simples assim .... hasuhduahd

Poxa vida, estou começando a ficar triste!!!

ultimamente só eu respondo meus topicos ahsdhasuhas

segue em anexo a solução:

   Private Sub SignXML(ByRef _pxml As XmlDocument, ByVal _cert As X509Certificate2, ByVal _puri As String)
        Try

            Dim _sig_xml As SignedXml
            Dim _ref As New Reference
            Dim _uri As XmlAttributeCollection
            Dim _xml_dig As XmlElement

            Dim x509data As New KeyInfoX509Data(_cert, X509IncludeOption.EndCertOnly)
            Dim keyinfo As New KeyInfo


            _sig_xml = New SignedXml(_pxml)
            _sig_xml.SigningKey = _cert.PrivateKey

            _uri = _pxml.GetElementsByTagName(_puri).Item(0).Attributes

            For Each _attr As XmlAttribute In _uri
                If _attr.Name = [Ô]id[Ô] Then
                    _ref.Uri = [Ô]#[Ô] + _attr.InnerText
                End If
            Next

            keyinfo.AddClause(x509data)

            _sig_xml.KeyInfo = keyinfo

            _ref.AddTransform(New XmlDsigEnvelopedSignatureTransform())

            _ref.AddTransform(New XmlDsigC14NTransform())

            _sig_xml.SignedInfo.AddReference(_ref)

            _sig_xml.ComputeSignature()

            _xml_dig = _sig_xml.GetXml()

            _pxml.DocumentElement.AppendChild(_pxml.ImportNode(_xml_dig, True))

        Catch ex As Exception
            Throw ex

        End Try
    End Sub
