IPSEC_LETSENCRYPT(8)

🌸 IPSEC_LETSENCRYPT(8) — the ipsec_letsencrypt page, bestie edition 🌸

okay so this is ipsec_letsencrypt from section 8 of the manual (that's the admin-commands girlies 💅), and honestly? she's here to make Opportunistic Encryption happen without you having a whole meltdown. let's get into it.

---

✨ NAME ✨

ipsec_letsencrypt — the little command that invokes the Opportunistic Encryption utilities 🎀

---

🦋 SYNOPSIS 🦋

ipsec letsencrypt [--client] [--server] [--test] [--disable] [--help]
      [--generate-certificate hostname] [--renew hostname]

that's the whole vibe. every flag, one line, iconic.

---

🌈 EXAMPLES 🌈

fr fr, here's how you actually run her:

ipsec letsencrypt { --client | --server | --test | --disable | -- help }

ipsec letsencrypt { --generate-certificate | --renew } hostname

like, pick your operation, or pick your operation plus a hostname. that's it. slay. ✨

💖 DESCRIPTION 💖

so <pink>Letsencrypt</pink> — yes, that's literally how the page starts, no cap — the command creates a secure Opportunistic Connection between the hosts, commonly referred to as client and server. and bestie, they are NOT the same energy:

• the client connects to the server and remains anonymous — she's mysterious, she's untraceable, she's giving main character in a hoodie 🕵️‍♀️
• the server is authenticated before you connect to it — she shows ID at the door, lowkey
• the server is not anonymous — we been knew
• the server uses Let's Encrypt certificates for authentication and encryption purposes — that's her whole thing 🔥

now the operations, one by one, no gatekeeping:

• --client — the operation used for initial client setup 🧚
• --server — the operation used for initial server setup 👑
• --test — the operation used for testing the configuration/connection ✅
• --generate-certificate hostname — generates the certificate for the hostname 🎀
• --renew hostname — updates the generated certificate... and it keeps the private key same 🔑 (yes, same key, that's the whole point, don't come for her)
• --disable — disables the IPsec service 💀
• --help — displays all the available options, aka her little menu of possibilities 🫶

ngl, --disable is the one that turns things OFF, so pls be intentional before you press it — she means it.
