It sounds backwards at first, right? Like how does sharing part of your encryption make things more secure? But that’s exactly how the internet works. It’s the magic of public-key cryptography.
You have a public key (which anyone can see) and a private key (which only you hold). People use your public key to send you encrypted messages but only your private key can unlock them. So yeah, by broadcasting that public part, you're actually locking down your info tighter, not exposing it.
Wild how that works, but it's the reason we can shop, bank, and message online without total chaos.

The security system that underlies the internet makes use of a curious fact: You can broadcast part of your encryption to make your information much more secure.
