https Radius authentication problem

Dear All Radius Developers, I am doing a web Radius authentication. I am also reading Mr. Alan DeKok's article about its security issue. https://github.com/FreeRADIUS/mod_auth_radius For http connection to the website, we know that the password is not encrypted. Now I set up a SSL certificate for the website in question. How do you rate the security of this https Radius authentication? Is the password, being sent over the internet, also encrypted by the usual SSL layer? Hope to receive your helpful response. Yours Faithfully, Timmy
