It doesn’t matter if the token was created on another server. You can still verify it if you have the right secret key and algorithm. Implementation with jsonwebtoken module client const {token} = sessionStorage; const socket = io.connect(‘http://localhost:3000’, { query: {token} }); Server const io = require(‘socket.io’)(); const jwt = require(‘jsonwebtoken’); io.use(function(socket, next){ if (socket.handshake.query … Read more

Yes. In general, you need to secure your login forms from CSRF attacks just as any other. Otherwise your site is vulnerable to a sort of “trusted domain phishing” attack. In short, a CSRF-vulnerable login page enables an attacker to share a user account with the victim. The vulnerability plays out like this: The attacker … Read more
Short answer JWTs are a convenient way to encode and verify claims. A Bearer token is just string, potentially arbitrary, that is used for authorization. Context (story time) A few years ago, before the JWT revolution, a <token> was just a string with no intrinsic meaning, e.g. 2pWS6RQmdZpE0TQ93X. That token was then looked-up in a … Read more
Generate a new token from GitHub’s developer settings Update the remote URL: git remote set-url origin https://<token>@github.com/<Git_URL> Pull once: git pull https://<token>@<Git_URL>.git And you are good to go.
const config = { headers: { Authorization: `Bearer ${token}` } }; const bodyParameters = { key: “value” }; Axios.post( ‘http://localhost:8000/api/v1/get_token_payloads’, bodyParameters, config ).then(console.log).catch(console.log); The first parameter is the URL. The second is the JSON body that will be sent along your request. The third parameter are the headers (among other things). Which is JSON as … Read more
I think it’s well explained here — quoting just the key sentences of the long article: The general concept behind a token-based authentication system is simple. Allow users to enter their username and password in order to obtain a token which allows them to fetch a specific resource – without using their username and password. … Read more
You can use the std::string::find() function to find the position of your string delimiter, then use std::string::substr() to get a token. Example: std::string s = “scott>=tiger”; std::string delimiter = “>=”; std::string token = s.substr(0, s.find(delimiter)); // token is “scott” The find(const string& str, size_t pos = 0) function returns the position of the first occurrence … Read more
