ienumerator.cls

这是一个在vb下实现的各种加密程序,可以实现一般的文本加密和文件加密,但是很多算法都是已经被人破解过的.

' This interface is used to allow for custom enumerators to be built.
'
' @remarks
' <p>The enumerator can be used manually to enumerate through the
' values of a list, or it can be wrapped in a custom enumerator to allow it to be
' used in the For..Each context.</p>
' <p>To use an IEnumerator object in For..Each, call the CreateEnumerator method
' passing in the IEnumerator object. The returned value is then returned in
' the standard NewEnum(-4) function called by For..Each. The enumeration will then
' be delegated to the custom IEnumerator object.<br><br>
' <b>Example</b><br>
' <pre>
' Public Function NewEnum() As IUnknown
'     Dim e As New MyEnumerator
'     e.Init Me
'     Set NewEnum = CreateEnumerator(e)
' End Function<br>
' </pre>
