<h1>Features</h1>
|

<p class="lede">Everything below is original, native Rust — the InspIRCd protocol and API are a
|
|
reference for wire compatibility, never a source of code.</p>

<h2>The daemon</h2>
|
|
<ul>
|
|
<li><strong>Safe by construction</strong> — <span class="mono">#![forbid(unsafe_code)]</span> across the whole tree, enforced in CI.</li>
|
|
<li><strong>Reactor core</strong> — a single core thread with a mio/epoll reactor pool; zero-copy broadcast lines and parallel large-channel fan-out.</li>
|
|
<li><strong>Full mode set</strong> — every standard channel and user mode, host cloaking, and custom prefixes.</li>
|
|
<li><strong>Operators</strong> — an InspIRCd-style privilege model: command grants, named privileges, and a usermode/chanmode allow-list per oper type.</li>
|
|
<li><strong>Edge</strong> — connection classes, per-class flood / fakelag, RFC 1413 ident, and PROXY protocol v1/v2 (with TLS TLVs).</li>
|
|
<li><strong>Observability</strong> — a metrics endpoint, structured JSON logging, and native syslog.</li>
|
|
</ul>

<h2>Transport & TLS</h2>
|
|
<ul>
|
|
<li><strong>6697</strong> direct TLS, <strong>7799</strong> WebSocket-over-TLS (wss), <strong>6667</strong> plaintext.</li>
|
|
<li>Two interchangeable backends — <strong>OpenSSL</strong> and <strong>rustls</strong> — both serving TLS 1.3.</li>
|
|
<li>With OpenSSL 3.5 the handshake negotiates post-quantum <span class="mono">X25519MLKEM768</span> key exchange.</li>
|
|
<li>Per-host <strong>SNI</strong> certificates, reloaded live on rehash.</li>
|
|

<h2>SASL</h2>
|
|
<ul>
|
|
<li><strong>PLAIN</strong> — classic username/password.</li>
|
|
<li><strong>EXTERNAL</strong> — authenticate by TLS client-certificate fingerprint.</li>
|
|
<li><strong>SCRAM-SHA-256</strong> — challenge/response, no password on the wire.</li>
|
|
<li><strong>ECDSA-NIST256P-CHALLENGE</strong> — sign a server challenge with a NIST P-256 key; the private key never leaves your client.</li>
|
|
</ul>
|
|
</div>
|
|
|
|
<div class="block">
|
|
<h2>Services</h2>
|
|
<ul>
|
|
<li><strong>NickServ</strong> — registration, grouped nicks, certificates, public keys, vhosts, profile metadata.</li>
|
|
<li><strong>ChanServ</strong> — founder/access, auto-op, akick, topic and mode locks.</li>
|
|
<li><strong>OperServ / MemoServ / more</strong> — network administration, offline messaging, and games.</li>
|
|
<li><strong>Event-sourced</strong> — every change is an appended event, replayed to rebuild state.</li>
|
|
<li><strong>SASL over S2S</strong> — the daemon relays mechanisms mechanism-agnostically; the services layer holds the credentials.</li>
|
|
</ul>

<h2>Security</h2>
|
|
<ul>
|
|
<li>A native anti-abuse engine in the core — not a bolt-on module.</li>
|
|
<li>Connection-flood and nick-flood detection, mass-join screening.</li>
|
|
<li>Behavioral and content heuristics with computed-pattern mining.</li>
|
|
<li>A DEFCON state machine and policy, plus DNSBL / MX-blacklist screening via a native async resolver.</li>
