(Xojo Plugin) 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.

// 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
success = zip.OpenZip("qa_data/hamlet.zip")
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

Dim entry As Chilkat.ZipEntry
entry = zip.GetEntryByName("hamlet.xml")
If (zip.LastMethodSuccess = False) Then
    System.DebugLog("Failed to find entry in zip")
    Return
End If

// lineEndingBehavior:
// 0 = leave unchanged.
// 1 = convert all to bare LF's
// 2 = convert all to CRLF's
Dim lineEndingBehavior As Int32
lineEndingBehavior = 0
Dim srcCharset As String
srcCharset = "utf-8"
Dim xmlText As String
xmlText = entry.UnzipToString(lineEndingBehavior,srcCharset)
System.DebugLog(xmlText)
