InlineEgg is a collection of python classes (a "library"), that will help you write small assembly programs, either to use as eggs/shellcode for your exploits or for anything else you may need small assembly programs for. However, without writing assembly, just using python.
InlineEgg is now included in CORE IMPACT as another component of its egg creation framework, but it started as a simple idea to fulfill a simple need. CORE hopes that you find it helpful for your own creations, so we are releasing it under an open source license for non-commercial uses.
