 It's only been a couple weeks since I installed my computer, and already my shell has been starting to lag. Since there's not that much I've put into my `.zshrc` file, I knew who the main culprits were. Namely, oh-my-zsh's "git" plugin and the nvm (node version manager) trying to load itself on startup. I'm not exactly in a situation where I need nvm most of the time I open my shell, so getting rid of that made my shell load a lot faster. It also means that every time I want to use node or npm, I'd have to manually call nvm, but that's not as important to me as a faster shell load time, especially since I don't really touch node that much.

 Obviously this is a pretty bruteforce-ish way to crack the cryptosystem, and probably won't work in time for you to see the result, but can still be considered an attack vector. This trick works by just factoring the modulus, N. With N, finding the private exponent d from the public exponent e is a piece of cake.

 My cryptography professor gave this example as well. Suppose there was a setup in which the modulus was reused, maybe for convenience (although I suppose with libraries today, it'd actually be more _inconvenient_ to reuse the key). Key pairs would be issued to different users and they would share public keys with each other and keep private keys to themselves.

 This attack is actually about RSA _signatures_ (which uses the opposite keys as encryption: private for signing and public for verifying), and shows how you can compute the signature of a message M using the signature of a derived message M'.

 If you think about it, a server waiting for clients is kind of like the host at the front of a restaurant leading guests to tables. They don't actually take orders or serve food, they just stand at the front and wait for new guests to arrive. Then there's another waiter that's specifically assigned to take that table's orders.

 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.
