(Delphi ActiveX) Create CAdES p7m using Azure Key Vault to Sign in the CloudSee more Signing in the Cloud ExamplesDemonstrates how to create a CAdES p7m, using Azure Key Vault. The signing of the hash happens in the Cloud on Azure Key Vault. Everything else regarding the creation of CAdES happens locally within Chilkat. Note: This example requires Chilkat v9.5.0.96 or greater.
