Demonstrates how to create a CAdES BES detached signature file (.p7s).

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim crypt As New Chilkat.Crypt2

// Use a digital certificate and private key from a PFX file (.pfx or .p12).
Dim pfxPath As String
pfxPath = "/Users/chilkat/testData/pfx/acme.pfx"
Dim pfxPassword As String
pfxPassword = "test123"

Dim cert As New Chilkat.Cert
Dim success As Boolean
success = cert.LoadPfxFile(pfxPath,pfxPassword)
If (success <> True) Then
    System.DebugLog(cert.LastErrorText)
    Return
End If

// Tell the crypt component to use this cert.
success = crypt.SetSigningCert(cert)
If (success <> True) Then
    System.DebugLog(crypt.LastErrorText)
    Return
End If

// The CadesEnabled property applies to all methods that create PKCS7 signatures. 
// To create a CAdES-BES signature, set this property equal to true. 
crypt.CadesEnabled = True

// We can sign any type of file, creating a .p7s as output:
Dim inFile As String
inFile = "/Users/chilkat/testData/pdf/sample.pdf"
Dim sigFile As String
sigFile = "/Users/chilkat/testData/p7s/sample.p7s"

// Create the detached CAdES-BES signature:
success = crypt.CreateP7S(inFile,sigFile)
If (success = False) Then
    System.DebugLog(crypt.LastErrorText)
    Return
End If

success = crypt.VerifyP7S(inFile,sigFile)
If (success = False) Then
    System.DebugLog(crypt.LastErrorText)
    Return
End If

System.DebugLog("Success!")
