Has anyone used AWS KMS? I would like to use AWS KMS to encrypt certain data in my database via an API call. I cannot see any examples of people doing this. It seem like it would be easy if Wappler supported AWS Signature in the API as a form of API authorization. I mainly want to use this to keep my encryptions as secure as possible. I suppose if I cannot figure out how to do this I can set up my own key management software that I host on a separate server to perform a similar task.
