Method of low-level encryption of section of website

I'm looking for a simple method of encrypting a small portion of my personal developer website. I'd like to display my resume directly on the site, but would prefer to protect it with a password so as to prevent those who are not potential employers from viewing it. What is a safe way of doing so while imposing a limited strain on potential employers (e.g. not requiring them to create an account)?

Notably, I will not be including information like my SSN or anything particularly sensitive -- just regular resume info. For this reason, would it be okay to provide all potential employers with the key, and rotating it every month-or-so?

I'm using Lit as a web component tool, but otherwise the site is vanilla JS + html.

Thanks for any guidance!
