Unzip an AES Encrypted Text File directly into a String Variable
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. Dim zip As New ChilkatZip2 Dim success As Long ' Any string unlocks the component for the 1st 30-days. success = zip.UnlockComponent("Anything for 30-day trial") If (success <> 1) Then MsgBox zip.LastErrorText Exit Sub End If ' 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("hamlet.zip") If (success <> 1) Then MsgBox zip.LastErrorText Exit Sub End If Dim entry As ChilkatZipEntry2 Dim xmlText As String Set entry = zip.GetEntryByName("hamlet.xml") If (Not (entry Is Nothing )) Then xmlText = entry.InflateToString2() Text1.Text = Text1.Text & xmlText & vbCrLf Else MsgBox "Failed to find entry in zip" End If |
