-- -X GET
-- -H "authorization:Px2e5oHhQZ88vVhc0DO%2FsShHj8MDDg%3DEXAMPLESIGNATURE"
-- -H "x-amz-pay-date:20201012T235046Z"

-- There are many other ways to load private keys into the Chilkat private key object, such as from different formats,
-- or from in-memory strings or bytes.

-- Note: When the private key is provided as shown above, Chilkat will automatically add the required x-amz-pay-* headers to the HTTP request,

-- x-amz-pay-date
-- x-amz-pay-host
-- x-amz-pay-region
-- Authorization
