I am working on doing an end-to-end encryption of data transfer between server and client..

Without touching the application code, can I add this as a layer in the API Gateway using some additional side car like Lambda ?

I am on AWS.

CodePudding user response：

You can't really do a sidecar Lambda in API Gateway. What you could do is send all your API Gateway traffic to Lambda, which could then issue requests to the backend application, obtain the results, and then encrypt the results before returning the response to API Gateway.
