Justin Richer OAuth 2 in Action

Produktbeskrivelse

DESCRIPTION OAuth 2 is like the web version of a valet key. Instead of unsafe password-sharing, OAuth offers a much more secure delegation protocol. OAuth is used everywhere, from large providers like Facebook and Google, to small APIs at startups, and even cloud services, it’s the worldwide standard. OAuth 2 is the must-know security protocol on the web today. OAuth 2 in Action teaches practical use and deployment of this protocol from the perspective of a client, authorization server, and resource server. It begins with an overview of OAuth and a look at its components and interactions. Using hands-on examples, it shows how to build a first OAuth client, followed by an authorization server, and then a protected resource. The second part of the book dives into crucial implementation vulnerability, and more advanced topics. By the end of this book, anyone will be able to build and deploy applications that use OAuth on both the client and server sides. KEY FEATURES • Hands-on examples • Connect with major online services like Google, Facebook, Twitter • Takes the reader from beginner to advanced OAuth 2 topics. AUDIENCE Readers need basic programming skills and knowledge of HTTP and JSON. ABOUT THE TECHNOLOGY This HTTP-based security protocol allows the users of a service to enable applications to use that service on their behalf without handing over full control. Web and mobile apps can securely access information from other servers for users, enabling apps to give these users functionality and services from other sites.
