How do you obfuscate a code?

Obfuscation techniques

1. Renaming. The obfuscator alters the methods and names of variables.
2. Packing. This compresses the entire program to make the code unreadable.
3. Control flow.
4. Instruction pattern transformation.
5. Dummy code insertion.
6. Metadata or unused code removal.
7. Opaque predicate insertion.
8. Anti-debug.

Why should one write clearly?

Writing clearly and concisely means choosing your words deliberately and precisely, constructing your sentences carefully to eliminate deadwood, and using grammar properly. By writing clearly and concisely, you will get straight to your point in a way your audience can easily comprehend.

Can obfuscated code be decompiled?

Obfuscation is the process of making code harder to understand in decompiled form, without changing the semantics. Others can make the code flow harder to follow, and some obfuscators can confuse some decompilers enough to stop them from being able to produce any code at all.

Can you obfuscate Javascript?

You can obfuscate the javascript source all you want, but it will always be reverse-engineerable just by virtue of requiring all the source code to actually run on the client machine… the best option I can think of is having all your processing done with server-side code, and all the client code javascript does is …

How to deal with obfuscation in a program?

A way to combat this type of obfuscation is to restore the original program by removing the unconditional branches or jumps. In comparison, the second method creates new generations by choosing and reordering the free instructions which have no impact on one another. It is a sophisticated and complex problem to find free instructions.

How is the quality of obfuscation technique determined?

The quality of an obfuscation technique should be determined by the combination of the following factors: This shows the extent to which the obfuscated code is different from the original code. The depth of control flows, nesting levels, and inheritance levels are used to increase the complexity of the source code.
