Default Easy to decompile
I was reading about cracking and how to prevent it. The article said that any software can be cracked and there is no 100% way to protect your software. Is this true? How can any software ever be sold if all software can be cracked?

It didn't go into detail but how can software be cracked anyway?

Decompiling to assembly is one way. .NET you can just decompile to original code.

All programs are in machine code/OS code. If you understand that, and most people don't, you can change it with a hex-editor to do something else. Back in the early 90's it was common to look up how to "crack" a program, and find directions to open the .exe with a hexeditor and change a 2-5 hex codes.

All you said is right but cracking is not easy. There is ways to make it hard for anyone want crack a program.
There is programs that decompile programs. But they are not complete even.

The only disassembler I ran into disassembled down to assembler. Whether that's easy to crack depends on your skill set.

There is the decompiler for .net that makes it easy to crack.

If you know assembly you can crack anything.
