Configure AWS Signature Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthAws, which associates an AuthAws provider so Chilkat signs each request using AWS Signature Version 4. The provider supplies the access key, secret key, region, and service name.

Use ChilkatAx-win32.pkg
