If I learn assembler...

[ttadast]

Hi. If I learn assembler language, I could edit and make my customs to .exe compiled files? For exapmle like server files or something?

yes, with a disassembler u can edit the source, however its a bunch of sh!t only few ppl can understand, so good luck with it.

Assembly is the language, not assembler.

And I suggest you look into reverse engineering, as that's what you'd want to learn about before jumping into Assembly.

Check this out.
A while ago when I was interested in RE someone suggested I learn C and x86 ASM first.
I managed to go through one C book before I realized it wasn't my thing.

As far as I see it, ASM/RE aren't difficult. Just plain boring and tedious.
You need a special mindset to become any good so to "edit and make my customs to .exe compiled files" you will need to spend several years studying the boring stuff first...

A good book in ASM is Art of Assembly(this book has it all from machine organization to advance assembly programming):
Art of Assembly Language Programming and HLA by Randall Hyde

Read About DOS 16 Bit Edition(the 32 bit edition speaks of HLA), but to start learning assembly you must have basic understanding of one of the high level programming languages, and always read about C and windows API(or C API's).

To find documentation about a function API , MSDN has a huge library about it.
MSDN – Explore Windows, Web, Cloud, and Windows Phone Software Development

You could try to read about AT&T Syntax too, with the Unix Sys Calls, and about GDB debugger.

i found some examples for your fun: Assembly sample code source code examples
xDDD

Learning assembly is to reverse code engineering as learning to drive is to professional rally racing.

It's something you have to learn, but once you know it, you aren't suddenly a reverse code engineer.

You can drive fast as soon as you can drive and may stay on the road if you're really lucky, but probably will blow the car and yourself up. Nice one.

When the language is as specific as Assembly, the code would be so complex, chances are you wouldn't even be able to find what you're trying to change in the first place.
