VBScript Requires Chilkat v11.0.0+

Unzip an AES Encrypted Text File directly into a String Variable

See more Zip Examples

A common need is to unzip from an AES encrypted Zip archive directly into a string variable, such that the unencrypted file never resides on disk, even temporarily. This example shows how to do it. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

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

set zip = CreateObject("Chilkat.Zip")

'  This example opens a WinZip-compatible AES encrypted
'  .zip that contains a single file: hamlet.xml.

'  It decrypts and unzips hamlet.xml directly into a string
'  variable.
zip.SetPassword "secret"
success = zip.OpenZip("qa_data/hamlet.zip")
If (success = 0) Then
    outFile.WriteLine(zip.LastErrorText)
    WScript.Quit
End If

set entry = CreateObject("Chilkat.ZipEntry")
success = zip.EntryOf("hamlet.xml",entry)
If (success = 0) Then
    outFile.WriteLine(zip.LastErrorText)
    WScript.Quit
End If

'  lineEndingBehavior:
'  0 = leave unchanged.
'  1 = convert all to bare LF's
'  2 = convert all to CRLF's
lineEndingBehavior = 0
srcCharset = "utf-8"
xmlText = entry.UnzipToString(lineEndingBehavior,srcCharset)
outFile.WriteLine(xmlText)

outFile.Close
