(VBScript) Create EBICS Signature (XMLDSIG)

See more EBICS Examples

Demonstrates how to create an EBICS signature. (EBICS is the Electronic Banking Internet Communication Standard)

Note: This example requires Chilkat v9.5.0.88 or above.

ActiveX for 32-bit and 64-bit Windows

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
