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);
}
}

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

Hope, this will help you out.
