C#.NET - how Obfuscator works

Hackers are barred from the source code via obfuscators. Data can be recovered using encryption and decryption techniques. These, though, do not constitute obfuscation. Hackers cannot access a programme that is disguised while it is still functioning as intended. Throughout the obfuscation process, optimisations are also applied to speed up the code.

Obfuscator merely converts all type names, namespace names, and other human-intelligible names to meaningless code. As a result, the possibility of reverse engineering is diminished.

Please see the below example,

private void AddEmp(Employee employee)
{
{
this.EmpList.Add(employee);
}
}

gets converted to
private void a(a b)
{
{
a.a.Add(b);
}
}
