Is It Safe to Use Public Wif?

Cryptography is the udy of sending messages through an adversarial environment. Messages going into and out of the ledger are not secret like that. I i'm confident in my cryptographic security with the ledger device, but there's other things that can happen. So i don't mind using public wife i. But if your esint public wyfi and your web side doesn't have h t t p s then people can just watch what's going on,. which has its own implications.
