What are ILDASM and Obfuscator in NET?

• ILDASM (Intermediate Language Disassembler)
  De-Compilation is the process of getting the source code from the assembly.
  ILDASM is a de-compiler provided by Microsoft.
  This ILDASM converts an assembly to instructions from which source code can be obtained.
• Obfuscated code is source code or intermediate language that is very hard to read and understand.
  An obfuscator is a medium of making a program difficult to understand.
  The way the code runs remains unaffected although the obfuscator makes it harder to hack the code and hijack the program.

Explain how Obfuscator works.

• Obfuscators protect the source code from being hacked. Encryption and Decryption are processes from where you can get the data back.
• However these differ from what obfuscation is. In obfuscation, a program become out of the reach of hackers although it functions the same way it is supposed to.
• Optimizations too get applied to the process of obfuscation in order to make the program fast.
