(VB.NET) Unzip an AES Encrypted Text File directly into a String VariableA 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.
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim zip As New 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") Dim success As Boolean = zip.OpenZip("qa_data/hamlet.zip") If (success <> True) Then Debug.WriteLine(zip.LastErrorText) Exit Sub End If Dim entry As Chilkat.ZipEntry = zip.GetEntryByName("hamlet.xml") If (zip.LastMethodSuccess = False) Then Debug.WriteLine("Failed to find entry in zip") Exit Sub End If ' lineEndingBehavior: ' 0 = leave unchanged. ' 1 = convert all to bare LF's ' 2 = convert all to CRLF's Dim lineEndingBehavior As Integer = 0 Dim srcCharset As String = "utf-8" Dim xmlText As String = entry.UnzipToString(lineEndingBehavior,srcCharset) Debug.WriteLine(xmlText) |
