Lua Requires Chilkat v11.0.0+

AWS KMS Import PFX Key

See more AWS KMS Examples

Imports a certificate's private key from a .pfx file to new key created in AWS KMS. Lua

local chilkat = require("chilkat")

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

-- Note: This example is using a relative file path.  You can also specify a full file path, such as "C:/someDir/myCertAndKey.pfx"
-- or a file path the makes sense on non-Windows operating systems..

local success = cert:load_pfx_file("qa_data/pfx/myCertAndKey.pfx", "pfx_password")

    return
end

-- Get the cert's private key.  This is what will be uploaded to AWS KMS.
