 Is your shell loading slower than it used to? Maybe you've been sticking a bit more into your `.bashrc`/`.zshrc` than you thought.

 The other day, I just turned off JavaScript from my browser. "fucking neckbeard", "you'll turn it back in 2 weeks", "living without JavaScript is like living without electricity" were some of the responses I got. And they might be right. But let's see why things are the way they are and what we can do about it.

 Procedural macros (proc macros for short) in Rust are incredible because they allow pre-compile source transformation. Many of the greatest abstractions in Rust take advantage of this feature. For example, you can

 The web is [so complicated][4] these days, I began wondering exactly how big of a feat it would be to formally verify everything. At this point I realized all I knew about web protocols were from fiddling around with HTTP 1.0 requests from doing CTFs in the past. You'd pop open a socket to wherever you wanted, stick `GET` and then whatever path you wanted, and then add a version number at the end.

 ### Encrypted tunnel
 
-Now we should be ready to communicate with the server through our encrypted tunnel. But we forgot to keep around our key negotiation parameters! How will we encrypt our communication? Let's go back and update these functions to let us keep the parameters, and then we can move on to implementing some of these crypto algorithms.
+Now we should be ready to communicate with the server through our encrypted tunnel. But we forgot to keep around our key negotiation parameters! How will we encrypt our communication? Let's go back and update these functions to let us keep the parameters, using the crypto functions we just defined.

+The key sharing function:
+
+```py
+def ext_key_share(Q):
+  kex = b"\x04" + Q.x + Q.y
+  key_share = struct.pack(">H", 23) + struct.pack(">H", len(kex)) + kex

+  return (struct.pack(">H", 51) # code number for alpn
+    + struct.pack(">H", len(ext))
+    + ext)
+```
+
+Finally, the new `client_hello_extensions`:
+
+```py
+def client_hello_extensions(hostname: str):
+  d, Q = ecdsa_keypair()
+  data = b"".join([
+    ext_supported_versions(),
