JwtSecurityTokenHandler and TokenValidationParameters

Question

I used to have a reference to Microsoft.IdentityModel.Tokens.JWT and everything was working fine.

I updated to use the new System.IdentityModel.Token

Answer 1

After a lot of research and tests, I finally found that some properties names for TokenValidationParameters had changed and JwtSecurityTokenHandler.ValidateToken() method signature too.

So here's the modified working version of the above code.

private static void ValidateJwt(string jwt)
{
    var handler = new JwtSecurityTokenHandler();   
    var validationParameters = new TokenValidationParameters()
    {
        ValidAudience = "https://my-rp.com",
        IssuerSigningTokens = new List() { new X509SecurityToken(
           X509
           .LocalMachine
           .My
           .Thumbprint
           .Find("UYTUYTVV99999999999YTYYTYTY88888888", false)
           .First()) },
        ValidIssuer = "https://my-issuer.com/trust/issuer",
        CertificateValidator = X509CertificateValidator.None,
        RequireExpirationTime = true
    };

    try
    {
        SecurityToken validatedToken;
        var principal = handler.ValidateToken(jwt, validationParameters, out validatedToken);
    }
    catch (Exception e)
    {

        Console.WriteLine("{0}\n {1}", e.Message, e.StackTrace);
    }

    Console.WriteLine();
}

And for the reference, the JwtSecurityTokenHandler lives in the System.IdentityModel.Tokens namespace. Don't forget to add the package "JSON Web Token Handler For the Microsoft .Net Framework 4.5" (version 4.0.0 at the time I write theses lines).

Hope it can save a few hours of search for some of you guys!
