hi, the question is very easy, i make a function for build a xml structure so i put it in a file and save it like xml. Easy, the problem is that i have to sign this file for send it to Italian Tax Agency and i have with me only a x509Certificate. On Internet i found that with only that i can sign the document but actually i dont know how.
Here my Complete Test Function:
How you can see there is actually a part of this XML that actually i have to Add with a directly Sign and is this:
So my question is actually, i wanna create a function that can Sign an XML and i still dont know how i can, maybe can give me some tips
or i dont know...i can share here a source of wiki about how should be work: https://en.wikipedia.org/wiki/XML_Signature
Here my Complete Test Function:
Generate XML:
Sub GetCertificatoX509 As String
If File.Exists(Comodo.PATHCORRISPETTIVI, "deviceCertificate.x509") Then
' Legge il contenuto del file
Dim fileContent As String = File.ReadString(Comodo.PATHCORRISPETTIVI, "deviceCertificate.x509")
' Divide il contenuto del file in righe
Dim lines() As String = Regex.Split(CRLF, fileContent)
' Verifica che ci siano almeno 3 righe (minimo per avere una seconda riga e una penultima riga)
If lines.Length > 2 Then
Dim result As StringBuilder
result.Initialize
' Aggiungi le righe dalla seconda alla penultima
For i = 1 To lines.Length - 2
result.Append(lines(i)).Append(CRLF)
Next
' Rimuove l'ultimo CRLF aggiunto
If result.Length > 0 Then
result.Remove(result.Length - CRLF.Length, result.Length)
End If
' Ritorna il risultato come stringa
Return result.ToString
Else
' Se ci sono meno di 3 righe, ritorna una stringa vuota
Return ""
End If
Else
' Se il file non esiste, ritorna una stringa vuota
Return ""
End If
End Sub
