【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 什么是JWT? Json web token (JWT), 是为了在网络应用环境间传递声明而执行的一种基于JSON的开放标准((RFC 7519).该token被设计为紧凑且安全的,特别适用于分布式站点的单点登录(SSO)场景。JWT的声明一般被用来在身份提供者和服务提供者间传递被认证的用户身份信息,以便于从资源服务器获取资源,也可以增加一些额外的其它业务逻辑所必须的声明信息,该token也可直接被用于认证,也可被加密。 jwt的组成 Header: 标题包含了令牌的元数据,并且在最小包含签名和/或加密算法的类型 Claims: Claims包含您想要签署的任何信息 JSON Web Signature (JWS): 在header中指定的使用该算法的数字签名和声明 示例: 1 2 3 4 5 6 7 8 9 10 11 12 13 Header: { "alg": "HS256", "typ": "JWT" } Claims: { "sub": "1234567890", "name": "John Doe", "admin": true } Signature: base64UrlEncode(Header) + "." + base64UrlEncode(Claims) 加密生成的token:

问题 I am using the jjwt Java library for server side generation of jwt in on servlets, the code snipper below straight from the jjwt GitHub page https://github.com/jwtk/jjwt generates and prints out this token. eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJKb2UifQ.XIKER3owR8BS3Krhsksg9INh9VBSejdn_qN-ONtPans String compactJws = Jwts.builder() .setSubject("Joe") .signWith(SignatureAlgorithm.HS256, "secret") .compact(); PrintWriter out = response.getWriter(); out.println(compactJws); However, when I try to verify

问题 I'm looking to implement JWT in my application for that I'm doing some R&D on it by taking a reference from : https://stormpath.com/blog/jwt-java-create-verify. I was successfully able to implement the generateToken() method, when I am trying to verifyToken() by extracting claim sets. I dont understand from where apiKey.getSecret() is came from. Could you please guide me on this? The code below for reference: public class JJWTDemo { private static final String secret = "MySecrete"; private

Static secret as byte[], Key or String?

I have started to work with JJWT to handle JWT on my server application. My JWT secret will be stored at resources folder and I will load the secret with Properties class. The JJWT provides three methods to sign the JWT, one uses byte[] , other uses String and the other uses Key : JwtBuilder signWith(SignatureAlgorithm var1, byte[] var2); JwtBuilder signWith(SignatureAlgorithm var1, String var2); JwtBuilder signWith(SignatureAlgorithm var1, Key var2); The question: Regarding security, charset and other things, there are any recommendations of which one I should use? For while, I stand with

Verifying JWT Signature using public key endpoint

问题 I'm wanting to verify the signature of some JWTs from Microsoft. I'm using Spring-Boot, the JJWT library and following endpoint: https://login.microsoftonline.com/common/discovery/v2.0/keys The endpoint returns an array of JSON public keys. Here is one example from the array. { "kty": "RSA", "use": "sig", "kid": "9FXDpbfMFT2SvQuXh846YTwEIBw", "x5t": "9FXDpbfMFT2SvQuXh846YTwEIBw", "n": "kvt1VmR4nwkNM8jMU0wmj2gSS8NznbOt2pZI6Z7HQT_esF7W19GZR7Y72Xo1i5zXRDM9o3GeTIjBrnr3yy41Q_EaUQ7C-b
