ReverseBox is a Python package with a set of functions useful in software reverse engineering.
Why ReverseBox?
It's designed to help with:
- Decompressing / compressing data
- Decrypting / encrypting data
- Tedious reverse engineering tasks e.g. testing different checksum algorithms to find the one that was used in the software or file format
- Figuring out file formats
- Parsing data structures
- Wrapping functions for input/output operations
- Searching for raw images
Who should use ReverseBox?
Mostly developers and reverse engineers (e.g. file format researchers
or software researchers).
