This document provides an overview of the OAuth authorization framework, including definitions of key terms like access tokens and request tokens. It explains the typical OAuth workflow using an example where a photo printing service (the consumer) wants access to a user's private photos (protected resources) hosted by a photo sharing site (the service provider). The workflow involves the consumer getting a request token, redirecting the user to authorize access, and then exchanging the authorized request token for an access token that can be used to access the protected resources. The document also covers OAuth security features like digital signatures and use of nonces and timestamps to prevent replay attacks.
Jane wants to share photos from Faji, a photo sharing site, with her grandmother using Beppa, a photo printing service. Beppa uses OAuth to access Jane's private photos on Faji without needing her username and password. Beppa first requests a request token from Faji, then redirects Jane to Faji for authorization. Jane approves access, and Beppa exchanges the request token for an access token to access Jane's photos and print them for her grandmother. OAuth allows Beppa to access protected resources like Jane's photos using tokens instead of her credentials.
Jane wants to share private vacation photos on Faji with her grandmother using a photo printing service called Beppa. Beppa uses OAuth to access Jane's photos without needing her Faji username and password. OAuth uses request tokens, access tokens, and digital signatures with shared secrets and nonces to authorize Beppa's access to Jane's private photos on Faji in a secure manner without revealing Jane's login credentials. Jane approves Beppa's access on Faji and is then able to view and order prints of her photos from Beppa.
Jane wants to share photos from Faji, a photo sharing site, with her grandmother using Beppa, a photo printing service. Beppa uses OAuth to access Jane's private photos on Faji without needing her username and password. Beppa first requests a temporary request token from Faji, then redirects Jane to Faji to approve access. After Jane approves, Beppa exchanges the request token for a long-term access token that it can use to access Jane's private photos and print them for her grandmother. OAuth allows Beppa to access protected resources like Jane's photos on Faji securely using tokens instead of her login credentials.

Introduce the new identity layers in OAuth2 that offer authentication on top of authorization - OpenId Connect and IndieAuth
Describes the role of OAuth.io in:
1. Standardizing all the different OAuth2 implementations of different providers, e.g., Facebook, Twitter, etc., by hiding them behind OAuth.io's API endpoints
2. Accelerating adoption of new OAuth2 standards by providing a shim layer to implement those standards on behalf of OAuth providers
OAuth 2.0 is for authorization, allowing third-party apps to access resources on a user's behalf. OpenID Connect builds on OAuth 2.0 by adding single sign-on and standardized ways to return identity information. It uses an ID token containing claims about the user. The authorization code flow involves the client app redirecting to the authorization server, which issues an authorization code back to the client after user consent. The client exchanges this code for an access token and ID token to call APIs. OpenID Connect adds userinfo and standard scopes to OAuth 2.0.
This slide deck gives an introduction to OAuth 2.0, starting with some concepts, explaining the flow plus a few hints. The reminder of the slides are about implementing an OAuth 2.0 server using the Apache Amber library (renamed to Apache Oltu lately). My impression is that many developers shy away as soon as they hear "security" and so I did not only want to talk about the concepts of OAuth 2.0 but also wanted to show how easily you can implement an OAuth 2.0 server ... hope it reduces the fear of contact a bit ... ;-)
The document provides an overview of the history and development of OAuth standards for authorization. It describes some of the issues with early implementations that prompted the creation of OAuth 1.0, including services storing user passwords and lack of ability to revoke access. OAuth 1.0 introduced signatures to address these issues. OAuth 2.0 replaced signatures with HTTPS and defines common flows for different use cases, including authorization code, implicit, password, and client credentials grants.
The OAuth 2.0 authorization framework enables a third-party
application to obtain limited access to an HTTP service, either on
behalf of a resource owner by orchestrating an approval interaction
between the resource owner and the HTTP service, or by allowing
the third-party application to obtain access on its own behalf.

My presentation outlining and explaining the core concepts behind OAuth, presented to the online ColdFusion Meetup June 9th 2011 and at Scotch on the Rocks, 3rd March 2011
OAuth2 Implementation Presentation (Java)Knoldus Inc.
The OAuth 2.0 authorization framework is a protocol that allows a user to grant a third-party web site or application access to the user's protected resources, without necessarily revealing their long-term credentials or even their identity. It is commonly used in scenarios such as user authentication in web and mobile applications and enables a more secure and user-friendly authorization process.
Authentication is the process of verifying a user's identity, while authorization determines what permissions and access levels a user has. Common authentication methods for APIs include basic authentication, bearer tokens, API keys, OAuth 2.0, and OpenID Connect. OAuth 2.0 allows users to grant third party applications access to their account without sharing their credentials. It involves the issuance of tokens that applications use to make API calls. OpenID Connect builds upon OAuth 2.0 to provide authentication for APIs as well by exchanging tokens that contain user identity claims.

The document provides an introduction to ASP.NET Core Identity and OAuth 2.0 authorization. It discusses Identity topics like user registration, sign in, the database schema, and dependencies. It also covers OAuth concepts like roles, tokens, registering as a client, authorization flows, and security vulnerabilities. The document is an introduction and overview of key Identity and OAuth concepts for a .NET Core training course.
OAuth is an authorization framework that enables third-party applications to obtain limited access to HTTP services. There are two versions, OAuth 1.0a and OAuth 2.0, which are completely different and not backwards compatible. OAuth 2.0 focuses on simplicity for client developers while providing authorization flows for different applications. OAuth is often referred to as a "valet key" for the web since it grants access to protected data only for specific uses and time periods.

Beppa must use OAuth to gain access to the photos in order to print them.
8. When Beppa added support for Faji photo import, a Beppa developer known in OAuth as a Consumer Developer obtained a Consumer Key and Consumer Secret from Faji to be used with Faji’s OAuth-enabled API. Using OAuth terminology, Consumer Key Consumer secret
9. Beppa requests from Faji a Request Token. At this point, the Request Token is not User-specific, and can be used by Beppa to gain User approval from Jane to access her private photos. Using OAuth terminology, Request Token
10. When Beppa receives the Request Token, it redirects Jane to the Faji OAuth User Authorization URL with the Request Token and asks Faji to redirect Jane back once approval has been granted to http://beppa.com/order. Using OAuth terminology, Oauth User Authorization URL Call Back URL
11. After successfully logging into Faji, Jane is asked to grant access to Beppa, the Consumer. Faji informs Jane of who is requesting access (in this case Beppa) and the type of access being granted. Jane can approve or deny access.
12. Jane waits for Beppa to present her with her photos fetched from her Faji account.
13. While Jane waits, Beppa uses the authorized Request Token and exchanges it for an Access Token. Request Tokens are only good for obtaining User approval, while Access Tokens are used to access Protected Resources, in this case Jane’s photos. In the first request, Beppa exchanges the Request Token for an Access Token and in the second (can be multiple requests, one for a list of photos, and a few more to get each photo) request gets the photos. Using OAuth terminology, Access Token
14. Jane is very impressed how Beppa grabbed her photos without asking for her username and password. She likes what she sees and place the print order.
15.
16. Tokens OAuth uses three types of credentials Client credentials (consumer key and secret) Temporary credentials (request token and secret) Token credentials (access token and secret)
17. Client Credentials Allows server to authenticate server Allows server to get information about the client Oauth_consumer_key Oauth_consumer_secret
18. Token Credentials Token credentials are in place of username and password The client uses token credentials to access resource owner protected resource Token credentials are limited in scope and duration Oauth_access_token Oauth_access_secret
19. Temporary credentials Used to identify the authorization request To accommodate different clients like desktop, mobile etc. Add extra flexibility and security Oauth_token Oauth_token_secret
21. Signature and Hash OAuth uses digital signatures instead of sending the full credentials (specifically, passwords) with each request. The sender uses a mathematical algorithm to calculate the signature of the request and includes it with the request.
22. Hash Algorithm A common way to sign digital content is using a hash algorithm. Hashing is the process of taking data (of any size) and condensing it to a much smaller value (digest) in a fully reproducible (one-way) manner This means that using the same hash algorithm on the same data will always produce the same smaller value Hashing usually does not allow going from the smaller value back to the original.
23. Shared Secret By itself, hashing does not verify the identity of the sender, only data integrity. In order to allow the recipient to verify that the request came from the claimed sender, the hash algorithm is combined with a shared secret If both sides agree on some shared secret known only to them, they can add it to the content being hashed.
24. Nonce(‘Number used Once’) What is missing is something to prevent requests intercepted by an unauthorized party, usually by sniffing the network, from being reused. This is known as a replay attack. Able to make the same sign request over and over again. To prevent compromised requests from being used again (replayed), OAuth uses a nonce and timestamp. By having a unique identifier for each request, the Service Provider is able to prevent requests from being used more than once
25. TimeStamp Using nonces can be very costly for Service Providers as they demand persistent storage of all nonce values received, ever. OAuth adds a timestamp value to each request which allows the Service Provider to only keep nonce values for a limited time. When a request comes in with a timestamp that is older than the retained time frame, it is rejected as the Service Provider no longer has nonces from that time period.
26. Signature Methods OAuth defines 3 signature methods used to sign and verify requests PLAINTEXT HMAC-SHA1 RSA-SHA1 When signing requests, it is necessary to specify which signature method has been used to allow the recipient to reproduce the signature for verification The decision of which signature method to use depends on the security requirements of each application
27. Signature Base String Not only must they both use the same algorithm and share secret, but they must sign the same content. This requires a consistent method for converting HTTP requests into a single string which is used as the signed content — the Signature Base String..
28. Getting the Request Token Building a reqestToken request requires the following: HTTP Method, Request URI, oauth_callback, oauth_consumer_key, oauth_nonce, oauth_signature_method, oauth_timestamp oauth_version
29.
30. Create your Authorization HTTP Header & and Issue the request Now we sign this string using our consumer secret and create an HTTP Authorization header. The signature should be placed in the oauth_signature value Getting the Request token
31. Now we issue this request to the requestToken endpoint, and if all is sucessful,you will get something like the following URL encoded response: The oauth_token field is now your request token, and the oauth_token_secret will be used for signing your request for an access toen.oaut_callback_confirmed just gives you confirmation the we recognized your oauth_callback parameter You will want to “hold on” to oauth_token and oauth_token_secret until you have completed the access token step Evaluate the Request Token
32. Now that we have a request token, we can build the url to authorize the user. we will then redirect the user to this url so they can grant your application access. An authorization url is simply this end point: https://api.twitter.com/oauth/authorize with a query parameter tacked on called oauth_token.the value for this parameter is equal to the request token you received in the previous step. The user needs to land on this page within 5 minutes of your request take cycle. you should not pass an oauth_callback parameter to this page(you already did that in the request token step) Authorizing the member Build your Authorization URL https://api.twitter.com/oauth/authorize?oauth_token=O6npS44e8ZPQfVcYfHVTGXtnLVBQ4xn8Wu2eBFtPNQ
33. Send the user to Twitter Authorization Page The user will then be sent to our authorization page. when completed the user will either be sent back to your oauth_callback URL or presented with a series of digits they will be instructed to hand-enter into your application(if you are performing out-of-band authentication) Authorizing the member
34.
35.
36. Prepare your singing secret Regardless of whether you used out-of-band authentication or not, you will now be equipped with a request token an oauth_token_secret and an oauth_verfier.you are now going to exchange that request token for an access token, imbued with permission of the Twitter member to act on their behalf Getting an Access token
37.
38. Create your Authorization HTTP Header & and Issue the request Now we sign this string using our request token secret and create an HTTP Authorization header. The signature should be placed in the oauth_signature value Getting the Access token
39. Now we issue this request to the aceessToken endpoint, and if all is sucessful,you will get something like the following URL encoded response: The oauth_token field is now your access token, and the auth_toke_secert will be used for signing all request on behalf of the member. You will want to “hold on” to oauth_token and oauth_token_secret until you have completed the access token step Evaluate the Access Token
44. Oauth is complicated, and there are a number of things that go wrong. Here are some tips. Every error response we send you will contain an xml body describing the error, including a timestamp representing server time. Some oauth-based requests will also return an OAUTH_PROBLEM http header Make sure that your server’s system clock is in sync with ours Oauth_callback should only be provided on the request token step. Oauth_verifier is required in the access Token. PUT & POST operations typically have xml content-types. your oauth library should exclude the request body in signature calculations as a result. For the access token step, remember that the request tokens oauth_token_secret must be used as part of your signing key Likewise, for all resource requests, your access tokens oauth_token_secret must be used as part of your signing key.
