Simple C# Code for JWT

Hi Geeks,

I just want to post a small post related to JWT code. Recently, when I was analyzing a web that use JWT to maintain its authentication and authorization, I found that having a good small code to generate your JWT token will help you to automate the token generation.

Below is small C# code to generate JWT token

using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;
using System.Text;
using Microsoft.IdentityModel.Tokens;

public class Generate
    public static void Main(String[] args)
        var tokenHandler = new JwtSecurityTokenHandler();
        var key = Encoding.ASCII.GetBytes("SecretMessageFromRio");
        var tokenDescriptor = new SecurityTokenDescriptor
            Subject = new ClaimsIdentity(new Claim[]
                new Claim(ClaimTypes.Name, "1")
            Expires = DateTime.UtcNow.AddDays(7),
            SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature)
        var token = tokenHandler.CreateToken(tokenDescriptor);
        var jwt = tokenHandler.WriteToken(token); Console.WriteLine(jwt);

You can use the code above and change the token secret keys with your own key.
