Hi Team, I have been working on REST Web SERVICES since a week, and Im really struck at this point. I want to create a REST API with the following sEt of rules: 1. All REST API calls must take place over HTTPS with a certificate signed by a trusted CA. All clients must validate the certificate before interacting with the server. 2. All REST API calls should occur through dedicated API keys consisting of an identifying component and a shared, private secret. Systems must allow a given customer to have multiple active API keys and de-activate individual keys easily. 3. All REST queries must be authenticated by signing the query parameters sorted in lower-case, alphabetical order using the private credential as the signing token. Signing should occur before URL encoding the query string. Any help would be really appreciated. Cheers!!
