A C# class that can sign and validate JWT tokens, wrapped in a simple library with a couple of helper functions.
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 using Newtonsoft.Json; JwtManager.RsJwt jwt = new JwtManager.RsJwt { KeySize = 256, // This can be also 384 or 512 PrivateKey = PrivateKey }; string strToken = JsonConvert.SerializeObject(myToken); string signedToken = jwt.Sign(strToken);In case of an error, an Exception will be thrown.
using Newtonsoft.Json; JwtManager.RsJwt jwt = new JwtManager.RsJwt { KeySize = 256, // This can be also 384 or 512 PublicKey = PublicKey }; string payload = jwt.Validate(strToken); var myToken JsonConvert.DesrializeObject<JwtToken>(payload);In case of an error, an Exception will be thrown.
The code has been tested both as a .NET and .NET Core library.
