hmac-js
A simple implementation of HMAC token generation and validation.
npm install hmac-js
or
yarn add hmac-js
Getting Started
This package needs some args:
- algorithm (string): can be sha256 or sha512;
- secret (string): your app secret key;
- payload (string): any data that you want;
- timestamp (integer): a valid timestamp;
In verifyHash method you can add an extra param, the ttl (hash life time). By default it is 30 seconds.
const Hmac = require('hmac-js');
const timestamp = new Date().getTime();
const hash = Hmac.generateHash({
algorithm: "sha512",
secret: "mysecret",
payload: "mypayload",
timestamp,
});
const isValidHash = Hmac.verifyHash(hash, {
algorithm: "sha512",
secret: "mysecret",
payload: "mypayload",
timestamp,
});
if (isValidHash) {
console.log("This is a valid hash");
} else {
console.log("This is an invalid hash");
}
That's all folks!
Simple as everything should be.
