I am newbie learning cracking need some help

Hello guys i am a newbie in cracking, i have read many tuts try`t many test cracks but all with some little explaining and that worked oke.
There are many programs that are not encrypted and can be read in kwsdm or ollydbg that is going oke but when it comes to other programs that are encrypted that is another story.
What i realy want is that someone can explain how to bypass the encrypted shit so that it is readeble in kwsdm or ollydbg.
I know that you use programs like imprec,lordpe,dillodumper,peid9,pe tools (Btw i have them all).
I don`t understand how to use oep or dumping a file to unpack it and that it then can be used with kwsdm or ollydbg.
If someone can explain how it works that would be great.
Mabye a little tutorial with a example file so that i can see how things work.

Thanks in advance.
