Escher - Stateless HTTP Request Signing
Escher is a stateless HTTP request signing spec to allow secure authorization and request validation. It adds an additional security layer and an authentication layer over HTTPS. The algorithm is based on Amazon's AWS4 authentication. The goal was implementing a protocol where request's integrity is validated. It is impossible to be modified without knowing the secret.
Escher is great for creating secure REST API servers, both the client side request signing process, and the server side validation and authentication processes are implemented. The protocol also provides a solution for presigning URLs with expiration time.
The status is work in progress. We're working on the documentation and finishing the first implementations.
Your help will be much welcomed, we are especially interested in code reviews and audits, new library implementations in different languages, writing the documentation and promotion.
