"e": "AQAB"JWKS - Json Web 密钥集是什么意思

{
  "keys": [
    {
      "kty": "RSA", #key type
      "e": "AQAB",  #Question - what does "e" mean or stand for. And what values can e take. What is AQAB here. 
      "use": "sig", #verify client assertion signature. This means what is the use of the key. Answer - to verify signature. Right?
      "kid": "somebase64encodestring", #key id
      "alg": "RS256",  #key algoritham. Here it is RSA.
      "n": "anotherbase64encodestring"  #This is the actual public key base64 encoded.
    } …

我收到两个JWT:一个OpenID Connect令牌(id_token)和一个访问令牌(access_token).OpenID的情况或多或少都很清楚 - 我可以使用JWKs Endpoint验证它:https://smth.com/JWKS .

例如(https://bitbucket.org/b_c/jose4j/wiki/JWT%20Examples):

HttpsJwks httpsJkws = new HttpsJwks("https://smth.com/JWKS");
HttpsJwksVerificationKeyResolver httpsJwksKeyResolver = new HttpsJwksVerificationKeyResolver(httpsJkws);
jwtConsumer = new JwtConsumerBuilder()
    .setVerificationKeyResolver(httpsJwksKeyResolver)
    .setExpectedAudience(...)
    .setExpectedIssuer(...)
    .build();

问题是如何继续使用访问令牌.我可以从中提取userId和userDetails,但我想我还需要验证它吗？

如果我尝试与令牌相同,我会收到错误:UnresolvableKeyException: Unable to find a suitable verification key for JWS w/ header {"alg" : "RS256", "kid":"1"}.事实上,"孩子"没有关键:"1",这个值"1"似乎有点奇怪？

我做错了吗？

我想生产JWT并用HMAC_SHA256签名.对于那个任务,我必须使用jose4j.我试图基于秘密生成密钥:

SecretKeySpec key = new SecretKeySpec(("secret").getBytes("UTF-8"), AlgorithmIdentifiers.HMAC_SHA512);

但是它会生成40位密钥,而使用HMAC_SHA256签名需要512位密钥.

• 主要问题 - 如何使用jose4j使用HMAC_SHA512签署令牌？
• 我上面的方法解决问题创建的问题 - 如何基于秘密字符串制作512位长密钥？

我正在使用jose4j来验证和处理JWT.JWT如下所示,它在JWT主页中通过验证.

但是,我不能用jose4j java库做同样的事情.异常抱怨我设置的验证密钥.但是库中定义了许多类型的键,我尝试过但没有运气.代码如下:

import java.util.Map;

import org.jose4j.jwt.JwtClaims;
import org.jose4j.jwt.consumer.InvalidJwtException;
import org.jose4j.jwt.consumer.JwtConsumer;
import org.jose4j.jwt.consumer.JwtConsumerBuilder;
import org.jose4j.keys.HmacKey;

public class YGJWT {

    public static void main(String args[]) throws InvalidJwtException {

        String jwt = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ";
        String secret = "secret";

        JwtConsumer jwtConsumer = new JwtConsumerBuilder()
                .setVerificationKey(new HmacKey(secret.getBytes())) //what kind of key do i need to use it here?
                .build();


        JwtClaims jwtClaims = jwtConsumer.processToClaims(jwt);
        Map<String, Object> claimsMap = jwtClaims.getClaimsMap();

        claimsMap.forEach((String key, Object val) -> {
            System.out.println(key + ": " + val.toString());
        });

    }

}

任何帮助表示赞赏.

如何在Java中验证Azure B2C id令牌的JWT签名？我已经使用google open-id connect成功验证了签名,但我还没有成功验证Microsoft Azure B2C jwt id令牌的签名.我在这里使用了示例B2C游乐场应用程序https://aadb2cplayground.azurewebsites.net/.注册并编辑我的个人资料后,我抓住了这个id令牌.

我需要从 JWT 中提取声明。

看来这应该是理所当然的事情。

它已签名，从我得到的标题中：

{
  "alg": "RS256",
  "typ": "JWT"
}

它在 jwt.io 网站上解码得很好，但由于我没有“秘密”密钥，所以它显示为“无效签名”。这很好，我不想验证它。

我想要的只是声明，但是当我使用 Java 库对其进行解码时，除了错误之外什么也没有得到。

如果我手动解码它（即 split/base64 解码），那就没问题了。

那么，我对 Java 库做错了什么？

我的 Java 应用程序正在接收 JWT。我有 PEM 格式的公钥：

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAixn0CGu8/M4txn4pdp8K

-----END PUBLIC KEY-----

我知道我可以使用 aJwtConsumer来验证和解码 JWT：

JwtConsumer jwtConsumer = new JwtConsumerBuilder()
    .setRequireExpirationTime()
    .setVerificationKey(publicKey) // what do I pass here?
    .build();

但是如何将我的 PEM 文件转换为.setVerificationKey().

我正在生成一个公钥/私钥对，我将使用它通过 jose4j 对 JWT 进行数字签名。它在创建和验证令牌方面也工作得很好。但是一旦我重新启动服务器，之前颁发的令牌就会失效。我觉得每次我重新启动服务器时它都会创建新密钥。这就是我在构造函数中生成密钥的方式：

    rsaJsonWebKey = RsaJwkGenerator.generateJwk(2048);
    // Give the JWK a Key ID (kid), which is just the polite thing to do
    rsaJsonWebKey.setKeyId("secretKey");

当我们尝试创建类的新实例时也会发生这种情况。它说令牌无效。

任何帮助，将不胜感激。谢谢..

参考这个,我必须使用算法AGCM256-KW加密.我正在使用Java Cryptography,我没有找到任何这样的算法.我发现最接近的是AES_256/GCM/NoPadding,但它没有KW(密钥包装).

这是我的测试代码

    public void testEncryption(String algo) {
    String shared_secret = "LyQnklSrxsk3Ch2+AHi9HoDW@//x1LwM123QP/ln";
    try {

        // Step 1 - Create SHA-256 digest of the shared key
        MessageDigest md = MessageDigest.getInstance("SHA-256");
        byte[] digest = md.digest(shared_secret.getBytes("UTF-8"));

        // Step 2 - generate a 256 bit Content Encryption Key(CEK)
        KeyGenerator kg = KeyGenerator.getInstance("AES");
        kg.init(256);
        SecretKey cek = kg.generateKey();

        // Step 3 - encrypt the CEK using 256 bit digest generated in Step 1
        // and 96 bit random IV. …

为了验证 JWT，我使用 jose4j 从 url 获取证书，在这种情况下，从谷歌：

    HttpsJwks httpsJkws = new HttpsJwks("https://www.googleapis.com/oauth2/v3/certs");
    HttpsJwksVerificationKeyResolver httpsJwksKeyResolver = new HttpsJwksVerificationKeyResolver(httpsJkws);
    //httpsJkws.setSimpleHttpGet(simpleHttpGet);
    JwtConsumer jwtConsumer = new JwtConsumerBuilder()
            .setVerificationKeyResolver(httpsJwksKeyResolver)
            .build(); // create the JwtConsumer instance

但是，这让我得到一个证书错误：

PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效认证路径

好的，是的，我可以使用一些脚本将它添加到 JVM 的信任库中，但我不想（基本上，它不是自签名证书，并且可以通过常规浏览器正常工作）。大多数时候，我使用 Apache HTTP 客户端 4.x，出于某种原因，在那里，调用确实可以正常工作：

    try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
        HttpResponse httpResponse = httpClient.execute(new HttpGet("https://www.googleapis.com/oauth2/v3/certs"));
        String response = (httpResponse.getEntity() != null) ? EntityUtils.toString(httpResponse.getEntity()) : null;
        log.debug(response);
    } catch (IOException e) {
        log.error("I/O Error when retrieving content from '" + jwksEndpointUrl + "': " + e.getMessage()); …

我正在尝试使用node.js中的jsonwebtoken验证jose4j生成的json Web令牌,我看到以下错误:

[错误:PEM_read_bio_PUBKEY失败]

jose4j代码基本上直接取自示例:

RsaJsonWebKey key = RsaJwkGenerator.generateJwk(2048);
