@cyberseckyle I like to read about the detailed mechanics of how security works, such as the #TLS protocol, #SSH, #livewire, #Goblins, ...

🌖 為什麼 SSH 每次按鍵會發送 100 個封包？
➤ 一次由 TCP 封包分析揭開的 SSH 安全機制探祕
✤ https://eieio.games/blog/ssh-sends-100-packets-per-keystroke/
作者在開發一款透過 SSH 運行的高性能文字介面遊戲時，發現伺服器 CPU 使用率異常高。透過 tcpdump 分析，他發現每次按鍵都會觸發約 100 個封包，其中包含大量 36 位元組的神祕訊息。深入調查後，他確認這並非遊戲程式的問題，而是 OpenSSH 本身的安全特性：為防止鍵入間隔時間洩漏隱私，SSH 會在每次按鍵後自動傳送大量「雜訊（chaff）封包」。作者最終透過在 SSH 連線中停用 `ObscureKeystrokeTiming` 選項，成功解決了遊戲的效能瓶頸。
+ 原來 SSH 還有這種隱藏的安全機制，為了防護隱私竟然會犧牲這麼多頻寬，真是長知識了！
+ 作者的偵錯過程太精彩了，從懷疑自己的程式碼到發現是 SSH 協定的特性，這種抽絲剝繭的分析能力真的很強。

TIL: You can really decrease the bandwidth of your SSH sessions by setting ObscureKeystrokeTiming no.
SSH has a feature where it will send a bunch of dud packets in the stream to make it harder for an attacker with TCP-level access to guess what you're typing just by watching the timing of your keystrokes. If you don't care, you can just tell it to stop sending the "chaff" packets.
I strongly suspect for most intranet use cases, this is fine.
🚀📡 Why does #SSH send 100 packets per keystroke? Because it loves a good workout, obviously! 💪🔄 Meanwhile, our brave investigator dives deep into #tcpdump territory, only to discover that the real mystery is why anyone cares. 🙄🔍

After many years of using SSH, I just realized that I don't need separate ssh key for each service on each machine.
Fuck me
Who do I know that's using Secretive to store #SSH keys in the #Mac secure enclave?
#sixels do “compress” image data by its nature design, #libsixel is highly optimized, on the other side #kittyterminal protocol
Direct transmission (t=d):
RGB/RGBA -> base64 … huge data transfer
RGB/RGBA -> PNG -> base64 … better in size, significant overhead
RGB/RGBA -> zlib compression -> base64 … also significant overhead
RGB/RGBA -> PNG -> zlib compression -> base64 .. even bigger overhead
Simple file transmission (t=f)
Client needs access to file … Forget about #ssh
Temporary file transmission (t=t)
Client needs access to /tmp, /dev/shm … forget about ssh
Shared memory object (t=s)
Client needs to have access to POSIX shared memory object/Windows named shared memory object … forget about ssh.
So yes, kitty is “superior” protocol with superior performance, except it works as “superior” only on localhost and event that is questionable at least in case of #brow6el (ok I acknowledge thats this is very specific “hack”)
