Hash Function Basics
A working note on how to compare common hash properties without overstating what they provide.
This note is an attempt to keep the basics straight.
Hash functions are often introduced as a convenient technical primitive, but the practical differences matter: output size, collision resistance expectations, speed, and the surrounding protocol context all change how the result should be interpreted.
The next step is to map these observations to concrete tools and examples instead of leaving them at the vocabulary stage.
