hash-calculation 0.0.3.post1

Calculate file hashes super fast!

File Hash Verification Tool

A Python-based file hashing tool with GUI and TUI modes, disk-aware chunk sizing utilities, and progress display.
Supports MD5, SHA1, SHA256, SHA512 for large files with noticeable speed improvements.

中文文档

Features

• GUI mode with Tkinter dialogs (falls back to TUI if Tk is unavailable)
• TUI mode with questionary prompts
• CLI arguments for direct calculation
• Disk-type detection helper for recommended chunk size (Windows only)
• Real-time progress bar with alive-progress
• Optional hash verification

Performance Comparison

The larger the file, the more pronounced the difference becomes.

Installation

pip install -r requirements.txt

Main dependencies:

• tkinter - GUI dialogs (standard library when available)
• questionary - TUI prompts
• alive-progress - Progress bar

Quick Start

GUI mode (default):

python -m hash_calculation

TUI mode:

python -m hash_calculation -t

CLI mode:

python -m hash_calculation -f "C:\path\to\file.iso" -m SHA256
python -m hash_calculation -f "C:\path\to\file.iso" -m SHA256 -c "your_sha256_hash"

Command Line Arguments

• -t, --tui Use TUI mode (interactive prompts)
• -f, --file File path for CLI mode
• -m, --mode Hash algorithm: MD5, SHA1, SHA256, SHA512
• -c, --compare Optional hash value to verify

Intelligent Chunking

On Windows, helper functions detect disk type to recommend chunk sizes:

• SSD: 512KB
• HDD: 256KB
• Fallback: 1MB when disk type is unknown

Non-Windows systems always use the default chunk size unless you pass a custom one.

Use as a Module

from hash_calculation import calculate_hash_with_progress, get_chunk_size, hash_diff
from pathlib import Path

file_path = Path("path/to/your/file")
algorithm = "SHA256"
chunk_size = get_chunk_size(file_path)
hash_value = calculate_hash_with_progress(file_path, algorithm, chunk_size=chunk_size)
# Optional: Calculate hash without progress bar
# from hash_calculation import calculate_hash
# hash_value = calculate_hash(file_path, algorithm, chunk_size=chunk_size)
print(f"{file_path}'s {algorithm} value is: {hash_value}")

compare_hash = "your_sha256_hash"
if hash_diff(hash_value, compare_hash):
    print("verification successful ✅")
else:
    print("verification failed ❌")

from hash_calculation import get_ssd_or_hdd

disk_types = get_ssd_or_hdd()
for disk, media_type in disk_types.items():
    print(f"Disk {disk}: {media_type}")

Notes

• Disk type detection only works on Windows
• Some environments may not return accurate disk media type
• Large directories are not supported as input; select files only
