正在开发应用程序，并且从一开始就希望获得安全性，因此我创建了一个私钥/公钥对，然后像这样设置passport-jwt：（key是密钥对的公开部分）
(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，我正在使用私钥对令牌进行签名，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);
}
});
});
});
我认为可能遗漏了一些东西，但是我不确定会是什么。
我还使用以下代码在初始化时也在应用程序内部生成了密钥。
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);
}
});
});
};

好的，所以这个问题有两个方面。首先，我为护照错误地生成了密钥。根据{{1}}，documentation的文档，密钥必须以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。 / p>
最终的解决方案包括使用keypair库，该库在npm上可用。
这是用于制作工作结果代码的修改。
passport-jwt密钥使用私钥签名，该私钥永远不会共享。
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);
}
});
});
};
以及验证功能：
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);
}
});
});
我希望这对希望将来使用非对称密钥的人有所帮助。

不错，这对我有帮助，谢谢。
如果它对其他人有帮助，我不必使用该库 - 找到了一个解释如何将公钥转换为 PEM 格式的链接，这似乎有效（私钥已经是正确的格式）
>ssh-keygen -f id_rsa.pub -m 'PEM' -e > id_rsa.pem
