Jwt Manager

I gathered my Sign and Validate functions for JWT tokens, wrapped them in a C# library among with a few helper functions and pushed all in a new repository in Github.

The solution consists of a .NET Core library and a Unit Tests project. You can open the solution with either Visual Studio or Visual Studio Code. For the time being, the unit tests runs on Windows.

To generate a compatible private key

openssl genrsa -out private.key 4096

To generate a compatible public key

openssl rsa -in private.key -outform PEM -pubout -out public.pem

Sign a JWT token

using Newtonsoft.Json;
 
JwtManager.RsJwt jwt = new JwtManager.RsJwt
{
    PrivateKey = PrivateKey
};
 
string strToken = JsonConvert.SerializeObject(myToken);
string signedToken = jwt.Sign(strToken);

Validate a JWT token

using Newtonsoft.Json;
 
JwtManager.RsJwt jwt = new JwtManager.RsJwt
{
    PublicKey = PublicKey
};
 
string payload = jwt.Validate(strToken);
var myToken JsonConvert.DesrializeObject<JwtToken>(payload);

Make sure to check the Readme.md and the unit tests to be aligned with any updates on how to create compatible keys and how to use them in your code.

Note also that the same code should work in a .NET project without the need to make any changes in the code.
