Need javascript/VB code to open password protected PDF file by passing password in code itself.

Question

Hi,
I have used PDFcreator to create the PDF file with password security
'To create PDF file with password security
With PDFCreator1
.cOption("UseAutosave") = 1
.cOption("UseAutosaveDirectory") = 1
' ==============
.cOption("AutosaveDirectory") = strBackupPath '& "\" & Format(Trim(Sheets("Form16_Database").Range("A" &
I).Value), "0#####") & "\" 'ActiveWorkbook.Path
Debug.Print Trim(Sheets("Form16_Database").Range("A" & I).Value) & "Form16-" & Format(Trim(Sheets
("Form16_Database").Range("A" & I).Value), "0#####") & "-" & Format(Now(), "YYYYMMDDHHMMSS") & ".PDF"
.cOption("AutosaveFilename") = Format(Trim(Sheets("Form16_Database").Range("B" & I).Value), "0#####") & ".PDF"
FileName = Format(Trim(Sheets("Form16_Database").Range("B" & I).Value), "0#####") & ".PDF"
.cOption("AutosaveFormat") = 0
.cOptions.PDFUseSecurity = 1
.cOption("PDFOwnerPass") = 1
.cOption("PDFOwnerPasswordString") = "mypass"
.cOption("PDFUserPass") = 1
.cOption("PDFUserPasswordString") = "mypass"
.cClearCache
End With

Now i am able to create PDF with Digital signature. But We want to assign password protection too..and problem is once we fix Digital signature we can't change security.
My problem is to pass password at the time of opening PDF for embedding signature. Password window should not prompt to the user while running VBA application.
Can you please help me to pass password on fly when file prompt password while opening PDF file. As file need to be opened at the time of fixing signature using sdk javascript code.

Answer 1

Correct, you need to encrypt then sign.
Unfortunately, there is no way to pass a password for opening.
