Whisper five. Last one.

Using SSH is required to open the door.

Hint:
Boring nerd stuff uncovers how to knock. Certificates are useful. Who issued them. Which SUBDOMAINS they cover.

For example, if you wanted to see Google's cert:

```bash
nmap -p 443 --script ssl-cert google.com
```

Google's cert has a lot of wildcards that cover many of their subdomains. Other certs call out specific names.

```bash
nmap -p 443 --script ssl-cert easyeasyspeakeasy.com
```

Look for names that sound like an entrance.

Don't have nmap? Sad.

See you inside.
