How to Bypass Web Restrictions to Discover Flags in CTF Challenges?


So this is the URL of the website (https://06bbe5b3978ba303a3f4fa5e605b8fe1-infosec-blog.web.cityinthe.cloud/) and I kinda tried everything without external tools but cannot find the flag.
There’s is a hint saying that "The author lays out some very interesting points about how to roll the crypto, people often reuse code, code that code snippet include important information?"

I’ve been trying to look at the source code and cookies, but didn’t see any information that I can decrypt with. the private key is at /keys/private and public keys is at keys/public.
PLZ HELP!
