(Unicode C) Sign XML (XAdES) in the Cloud using Azure Key Vault

See more Signing in the Cloud Examples

Demonstrates how to sign XML using Azure Key Vault. The signing of the hash happens in the Cloud on Azure Key Vault. Everything else involving the updating the XML to add the signature happens locally within Chilkat.

Note: This example requires Chilkat v9.5.0.96 or greater.
