    ValidIssuer = ValidIssuer,

    ValidateAudience = false,
    ValidAudience = ValidAudience,

    ValidateIssuerSigningKey = false,
    //IssuerSigningKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(SecretKey)),

    SignatureValidator = delegate(string token, TokenValidationParameters parameters)
    {
        var jwt = new JwtSecurityToken(token);

        return jwt;
    },

    RequireExpirationTime = true,
    ValidateLifetime = true,

    ClockSkew = TimeSpan.Zero,
    };

    result.RequireSignedTokens = false;

    return result;
}
