# Excel Password Cracker
A simple brute-force attack password cracker for Excel files with multi-threaded implementation optimizing performance.
This tool simply generates a sequence of words (including numbers) following the predefined character combination, and attempts to decrypt Excel file with each password until the correct one is found.
Brute-force is not the most efficient algorithm out there, so keep in mind that this tool is limited to be functional with simple passwords.
## Todo
- [ ] Save decrypted file
- [ ] Progress info
- [ ] Easier selection of characters for generator
- [ ] Dictionary attack
- [ ] Code readability
- [ ] Heuristics
- [ ] Benchmarks
- [ ] Save last position
- [ ] Possibility to restart form last position
