Obfuscation – heard it, learn it!


Obfuscation is the act of rendering virtually anything, not understandable.  Code obfuscation is where programmers code in such a way that no other programmers can understand.  According to wikipedia..

Obfuscated code is source or machine code that has been made difficult to understand for humans. Programmers may deliberately obfuscate code to conceal its purpose (security through obscurity) or its logic to prevent tampering, deter reverse engineering, or as a puzzle or recreational challenge for someone reading the source code. Programs known as obfuscators transform readable code into obfuscated code using various techniques. Code obfuscation is different in essence from hardware obfuscation, where description and/or structure of a circuit is modified to hide its functionality.

Below is a 1988 entry which calculates pi by looking at its own area:

#define _ -F<00||--F-OO--;
int F=00,OO=00;main(){F_OO();printf("%1.3f\n",4.*-F/OO/OO);}F_OO()
