# File Hasher Tool

## Description
Calculate cryptographic hashes for files to verify integrity, detect duplicates, or generate checksums.

## Trigger
- `/hash` command
- User needs file checksums
- User wants to verify file integrity

## Usage

```bash
# Calculate SHA256 hash
python scripts/file_hasher.py file.zip

# Calculate multiple hash types
python scripts/file_hasher.py file.zip --all

# Verify against known hash
python scripts/file_hasher.py file.zip --verify abc123...

# Hash multiple files
python scripts/file_hasher.py *.zip --algorithm sha256

# Find duplicate files
python scripts/file_hasher.py --find-duplicates ./folder/
```
