Rust Requires Chilkat v11.5.0+

XAdES XML Signature using ARSS (Aruba Remote Signing Service)

See more Signing in the Cloud Examples

Demonstrates how to sign XML using ARSS (Aruba Remote Signing Service). Rust

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

// --------------------------------------------------------------------------------
// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.
// --------------------------------------------------------------------------------

// Create the XML to be signed.

// authentication is validated.  The correct value depends on the type
