Rate different types in reversing ?

[Jasi2169]

Hi guys as we know there are different types of cracking method for software, lets rate it

0. UNPACKING

1. KEYGENNING
2. PATCHING
3. CRACKING
4. HOOKING USING DLL/or javaagent etc any hooking/ loader
5. SERIAL

According to me; Unpacking is different but its on top, but letsvtalk about only general cracking methods, dont take unpacking/cryptog. Inside, you might have your own personal love for something, yes its not always available to do keygenning and other various factors like hardware lock/server check, but simple scenarios

Keyegnning > hook > serial > patching > cracking

I know cracking is only limited to one version most of the time and sometimes it's not possible to keygen or anything due to online or server checks or packing and we left with it.
