binary machine code

基本解释

Often the target language is a binary format like machine code, but not always.
目標語言通常爲二進制格式（如機器代碼），但不縂是這種格式。
Is executed by the shell, then passed to the kernel, which is typically slower than a compiled binary program that is pure machine code.
由 shell 執行，然後傳遞給內核，這個過程通常比編譯爲純機器碼的二進制程序慢。
My understanding is that the application binary is already encrypted by the time it gets to a user device but this is only the binary and the machine code can still be accessed.
我的理解是，應用程序已經通過它得到一個用戶裝置，但這僅是二進制機器代碼仍然可以訪問加密的時間。
