node.js - 带有护照 jwt 的非对称 key 。验证总是返回 Unauthorized

Question

在应用程序上工作，我从一开始就想要安全，所以我创建了一个私钥/公钥对，我正在设置 passport-jwt像这样:(key 是 key 对的公共(public)部分)

(passport, key) => {
  const opts = {
    jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
    secretOrKey: key
  };
   passport.use(
     new JwtStrategy(opts, (payload, done) => {
       log.info({message: 'verifying the token', payload});
       User.findById(payload.id)
         .then(user => {
           if (user) {
             return done(null, {
               id: user._id,
               name: user.userName,
               email: user.emailAddress
             });
           }
           log.info(payload);
           return done(null, false);
         })
         .catch(err => {
           log.error(err)
           return done('Unauthorized', false, payload);
          });
     })
   );
};

当用户登录时，我使用私钥签署 token ，如下所示:

router.post('/login', (req, res) => {
        const email = req.body.email;
        const password = req.body.password;

        User.findOne({ email }).then(user => {
            if (!user) {
                errors.email = 'No Account Found';
                return res.status(404).json(errors);
            }

            bcrypt.compare(password, user.password).then(isMatch => {
                if (isMatch) {
                    const payload = {
                        id: user._id,
                        name: user.userName,
                        email: user.emailAddress
                    };
                    log.info(payload);
                    jwt.sign(payload, private, { expiresIn: 30000000 }, (err, token) => {
                        if (err)
                            res.status(500).json({ error: 'Error signing token', raw: err });
                        // const refresh = uuid.v4();
                        res.json({ success: true, token: `Bearer ${token}` });
                    });
                } else {
                    errors.password = 'Password is incorrect';
                    res.status(400).json(errors);
                }
            });
        });
    });

我想我可能缺少一些东西，但我不确定它可能是什么。

此外，我也一直在使用以下代码在初始化时在应用程序内生成 key 。

const ensureKeys = () => {
    return new Promise((resolve, reject) => {
        ensureFolder('./keys').then(() => {
            /**
             * Ensure that both the private and public keys
             * are created, and if not create them both.
             * Never generate just a single key.
             */
            try {
                if (
                    !fs.existsSync('./keys/private.key') &&
                    !fs.existsSync('./keys/public.key')
                ) {
                    log.info('Keys do not exist. Creating them.');
                    diffHell.generateKeys('base64');
                    const public = diffHell.getPublicKey('base64');
                    const private = diffHell.getPrivateKey('base64');
                    fs.writeFileSync('./keys/public.key', public);
                    fs.writeFileSync('./keys/private.key', private);
                    log.info('keys created and being served to the app.');
                    resolve({ private, public });
                } else {
                    log.info('keys are already generated. Loading from key files.');
                    const public = fs.readFileSync('./keys/public.key');
                    const private = fs.readFileSync('./keys/private.key');
                    log.info('keys loaded from files. Serving to the rest of the app.');
                    resolve({ private, public });
                }
            } catch (e) {
                log.error('issue loading or generating keys. Sorry.', e);
                reject(e);
            }
        });
    });
};

Answer 1

好的，所以问题是双重的。首先，我为护照错误地生成了 key 。根据 passport-jwt 的文档, documentation ， key 必须以 PEM 格式编码，并且根据 Medium 上的这篇文章，需要对护照和 JWT 进行更多配置。

最终解决方案包括使用 keypair 在 npm 上可用的库。

以下是用于制作工作结果代码的修改。

const keypair = require('keypair');
const ensureKeys = () => {
    return new Promise((resolve, reject) => {
        ensureFolder('./keys').then(() => {
            /**
             * Ensure that both the private and public keys
             * are created, and if not create them both.
             * Never generate just a single key.
             */
            try {
                if (
                    !fs.existsSync('./keys/private.key') &&
                    !fs.existsSync('./keys/public.key')
                ) {
                    log.info('Keys do not exist. Creating them.');
                    const pair = keypair();
                    fs.writeFileSync('./keys/public.key', pair.public);
                    fs.writeFileSync('./keys/private.key', pair.private);
                    log.info('keys created and being served to the app.');
                    resolve({ private: pair.private,public: pair.public });
                } else {
                    log.info('keys are already generated. Loading from key files.');
                    const public = fs.readFileSync('./keys/public.key', 'utf8');
                    const private = fs.readFileSync('./keys/private.key', 'utf8');
                    log.info('keys loaded from files. Serving to the rest of the app.');
                    resolve({ private, public });
                }
            } catch (e) {
                log.error('issue loading or generating keys. Sorry.', e);
                reject(e);
            }
        });
    });
};

key 是用永远不会共享的私钥签名的。

    router.post('/login', (req, res) => {
        const { errors, isValid } = require('../validation/user').loginUser(
            req.body
        );
        if (!isValid) {
            return res.status(400).json(errors);
        }
        const email = req.body.email;
        const password = req.body.password;

        User.findOne({ email }).then(user => {
            if (!user) {
                errors.email = 'No Account Found';
                return res.status(404).json(errors);
            }

            bcrypt.compare(password, user.password).then(isMatch => {
                if (isMatch) {
                    const payload = {
                        id: user._id,
                        name: user.userName,
                        email: user.emailAddress
                    };
                    log.info(payload);
                    jwt.sign(payload, private, { 
                        expiresIn: 30000000,
                        subject: user.emailAddress,
                        algorithm: 'RS256'
                     }, (err, token) => {
                        if (err)
                            res.status(500).json({ error: 'Error signing token', raw: err });
                        res.json({ success: true, token: `Bearer ${token}` });
                    });
                } else {
                    errors.password = 'Password is incorrect';
                    res.status(400).json(errors);
                }
            });
        });

以及验证功能:

  const opts = {
    jwtFromRequest: ExtractJwt.fromAuthHeaderWithScheme('Bearer'),
    secretOrKey: key,
    algorithm: ["RS256"]
  };
passport.use(
     new JwtStrategy(opts, (payload, done) => {
       log.info({message: 'verifying the token', payload});
       User.findById(payload.id)
         .then(user => {
           if (user) {
             return done(null, {
               id: user._id,
               name: user.userName,
               email: user.emailAddress
             });
           }
           log.info(payload);
           return done(null, false);
         })
         .catch(err => {
           log.error(err)
           return done('Unauthorized', false, payload);
          });
     })
   );

我希望这可以帮助任何希望在 future 使用非对称 key 的人。
