alpha_decoder is a Rust command-line tool for decoding Alpha2-based shellcode.
- Mixed-case ASCII
- Uppercase ASCII
- Mixed-case Unicode
- Uppercase Unicode
This tool is currently a work-in-progress. Here is a rough to-do list:
- Implement remaining formats (see above)
- Create a proper API for identifying and parsing Alpha2 formats
- Expose more information about Alpha2 payloads to the user
- Expose functionality as a crate
- Add tests
