- Compressing Import Section
Maybe more properly named "How to Remove Imports and Rebuild IAT Manually at Runtime".
This is a quick paper and sample implemenation on how you can remove all of the imports from an exe and then load them manually yourself at runtime. This is a step often involved when creating trial ware wrappers or trying to "crack proof" your software.
For clarity the code is implemented as a dll and does not actually compress the API function names list.
