我们在前面了解到,Authorization Code 模式是最安全的一种模式,但是必须要有服务端参与进来,因为 client_secret 必须保存在服务端才安全。OAuth 2.0 在 RFC7636 中定义了一种扩展模式,这种模式下,客户端不需要使用 client_secret,模式中 PKCE 的全称是 Proof Key for Code Exchange。那怎么理解这个呢?简单来说,就...
The Authorization code flow with PKCE. In addition to an authorization code, a code challenge and code verifier are also required Proof Key for Code Exchange is an extension of theOAuth 2.0specification that adds an extra layer of security using a locally generatedcode_verifieran...
以下是使用Java实现Authorization Code Flow with PKCE的示例代码。在这个示例中,我们使用了OkHttp和Java的内置库来进行HTTP请求和SHA-256哈希计算。请注意,这只是一个简单的示例,实际应用中可能需要更多的错误处理和安全性措施。 import okhttp3.*; import java.security.MessageDigest; import java.security.NoSuch...

安全性增强:OAuth 2.1在安全性方面引入了一些增强功能,以强化协议的安全性。这些增强功能包括:禁止使用基于浏览器的应用程序进行授权码授权流程(Authorization Code Flow with Proof Key for Code Exchange, PKCE),推荐使用强密码散列算法等。 便捷性:OAuth 2.1的目标之一是简化开发者对OAuth 2.0的实现和使用。它提供了...
改为用 :Authorization Code + PKCE Password的问题# 园友已经说的很清楚了我总结下; 1、最大的问题就是违背了委托授权的原则,比如我的Web服务用微信登录用的Password flow的话,那意思是需要在我的登录页面里面填写微信的账号和密码,这眼见的不可思议和不合理吧; ...
authorization code with pkce代码 一、简介 PKCE(Protocol Key Code Exchange)是一种用于OAuth 2.0的增强机制,用于保护客户端应用程序免受滥用OAuth 2.0授权码的风险。在本文中,我们将介绍PKCE代码的基本概念、实现步骤以及如何将其应用于实际场景中。 二、PKCE代码基本原理 PKCE代码的主要目的是确保OAuth 2.0授权码的...

Apps currently using the implicit flow to get tokens can move to the spa redirect URI type without issues and continue using the implicit flow. Despite this backward compatibility, we recommend that you use the auth code flow with PKCE for SPAs....
