XML Signature Multiple External References
See more XML Digital Signatures Examples
Demonstrates how to add multiple external references to an XML digital signature.Chilkat Rust Downloads
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// This example creates the following signed XML with multiple external references:
