Create Password Protected Zip containing a Single File.

Create a password-protected .zip containing a single file. (This uses the older Zip 2.0 encryption scheme, which is weaker and not as secure as AES encryption, which Chilkat Zip also supports.)

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

success = zip.NewZip("test.zip")
If (success <> 1) Then
    MsgBox zip.LastErrorText
    Exit Sub
End If

zip.SetPassword "secret"
zip.PasswordProtect = 1

Dim saveExtraPath As Long
saveExtraPath = 0
success = zip.AppendOneFileOrDir("c:/temp/hamlet.xml",saveExtraPath)

success = zip.WriteZipAndClose()
If (success <> 1) Then
    MsgBox zip.LastErrorText
    Exit Sub
End If

MsgBox "Zip Created!"
