Chapter 1: C/C++

Installation and usage

1. Please copy the Securepass_auth.h header file and the radclt.lib library file into your project.
2. Please perform authentication through the SecuAuth interface. For detailed instructions, please see the demo project.


How to integrate with the C++ environment

1. Please add the RadiusClt1.h header file and radclt.lib library file to the project.

2. When you need to perform authentication, instantiate the RadiusClt class.
3. Use the initrad member function inside the RadiusClt class to initialize authentication information.
4. Use the “parase” member function inside the RadiusClt class in order to set the username and OTP PIN for authentication. Use the “auth” member function inside the RadiusClt class to terminate the authentication process.

Chapter 2: C#

Installation and usage

1. Please add the UniOTP_Clt.dll dynamic library to your project.
2. Instantiate the SecuRadClts_Client constructor class in your source code where you want to authenticate the user.
3. Use the “Authenticate” method inside the SecuRadClts_Client class to perform the authentication

For further details about the source code, please see the sample folder.

SecuRadClts_Client class performs Radius client functions. By calling the member class function interfaces below, you can perform standard Radius authentication.
