What is Oz?
According to the Oz README:
Oz is a web authorization protocol based on industry best practices. Oz combines the Hawk authentication protocol with the Iron encryption protocol to provide a simple to use and secure solution for granting and authenticating third-party access to an API on behalf of a user or an application.
Oz and OAuth 2.0
Oz is an alternative to OAuth 1.0a and OAuth 2.0 three-legged authorization. One of the goals of Oz is to be simple to use for the most common use cases without needing to be a web security expert while being flexible enough for less common use cases that may need more advanced web security knowledge. Oz does this by providing default options that are secure for the most common use cases, in other words Oz aims to be secure by default.
All of the official three-legged OAuth 2.0 grant types have an equivalent Oz workflow. Below is table showing the Oz workflow equivalents for the OAuth 2.0 grant types.
OAuth 2.0 Grant Type | Oz Workflow |
---|---|
Authorization Code | RSVP |
Implicit/PKCE | Implicit (Not an official workflow) |
Resource Owner Password Credentials | User Credentials (Not an official workflow) |
Client Credentials | Hawk |
