How the internet works
What really happens between your computer and a website, who takes part, and what each of them can see.

7 分钟 - 3 HTTPS and certificates: what the padlock proves and what it doesn’t
What TLS actually does, what a certificate really certifies, and why the padlock is not a verdict on whether a site is trustworthy.
8 分钟 - 4 VPNs, Tor and proxies: who you shift trust to
