Hi Mahesh, You need to use JWTSecurityTokenHandler class to generate JWT Token in ASP.Net core. Below is the documentation of the class https://docs.microsoft.com/en-us/previous-versions/visualstudio/dn464181(v%3Dvs.114) Below is the quick sample of what you need to do in order to generate the JWT token in ASP.Net core API https://salslab.com/a/jwt-authentication-and-authorisation-in-asp-net-core-web-api Hope, this will help you out.

Hi Mahesh the code i tried public string CreateToken() { string privateKey = File.ReadAllText(@""); loginName = _configuration["Tokens:SandboxTestUser"]; issuerId = _configuration["Tokens:IssuerId"]; var t = DateTime.UtcNow - new DateTime(1970, 1, 1); int iat = (int)t.TotalSeconds; var payload = new JwtPayload { { "iss", issuerId}, { "iat", iat }, { "exp", iat + 1800}, { "sub", loginName } }; RSAParameters rsaParams; using (var tr = new StringReader(privateKey)) { var pemReader = new PemReader(tr); var KeyParameter = (Org.BouncyCastle.Crypto.AsymmetricKeyParameter)pemReader.ReadObject(); var privateRsaParams = (RsaPrivateCrtKeyParameters)KeyParameter; rsaParams = DotNetUtilities.ToRSAParameters(privateRsaParams); } using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider()) { rsa.ImportParameters(rsaParams); // Dictionary payload = claims.ToDictionary(k => k.Type, v => (object)v.Value); return Jose.JWT.Encode(payload, rsa, Jose.JwsAlgorithm.RS512); } }
