Auth Token Generator

Auth Token Generator is a Dart package for generating and validating bearer tokens using HMAC-SHA256 encryption.

Installation

To use this package, add auth_token_generator as a dependency in your pubspec.yaml file:

dependencies:
  auth_token_generator: ^1.1.0

Then, import the package in your Dart code:

import 'package:auth_token_generator/auth_token_generator.dart';

Usage

Generating Bearer Tokens

You can generate bearer tokens using the generateBearerToken method: final secretKey = 'my_secret_key'; final userId = 'user123'; final token = AuthTokenGenerator.generateBearerToken(secretKey, userId: userId); print('Generated token: $token');

Extracting User ID from Bearer Tokens

You can extract the user ID from a bearer token using the getUserIdFromBearerToken method:

final extractedUserId = AuthTokenGenerator.getUserIdFromBearerToken(secretKey, token); if (extractedUserId != null) { print('Extracted user ID: $extractedUserId'); } else { print('Invalid token or signature.'); }

Validating Bearer Tokens

You can validate bearer tokens using the validateBearerToken method:

final isValid = AuthTokenGenerator.validateBearerToken(secretKey, token); print('Is the token valid? $isValid');

Checking Token Expiration

You can check if the token has expired using the isTokenExpired method:

final isExpired = AuthTokenGenerator.isTokenExpired(token); print('Is the token expired? $isExpired');

Decoding Bearer Tokens

You can decode a bearer token without validating the signature using the decodeBearerToken method:

final decoded = AuthTokenGenerator.decodeBearerToken(token); print('Decoded token: $decoded');
