## What it is
Masuit.Tools is a Swiss-army utility library for C#/.NET bundling dozens of commonly needed helpers: encryption, reflection, LINQ and expression-tree extensions, file compression, multithreaded/resumable downloads, hardware info, Chinese lunar calendar, image cropping, captcha generation, and Excel export. It targets .NET Framework 4.5 through .NET 8 via several NuGet packages while staying under 2MB of code.

## Use cases
- encrypt and decrypt strings in a .NET app
- export data to Excel from C#
- download large files with multithreading and resume support
- get hardware information in .NET
- convert dates to the Chinese lunar calendar
- crop images and generate captchas in C#
- extend LINQ and collections with helper methods
- generate distributed short IDs

## When to choose
- you want one small dependency covering many common .NET utility needs
- you need Chinese-lunar-calendar or China-specific helpers
- you want extension methods for strings, dates, and collections without writing them yourself

## When to avoid
- you prefer minimal, single-purpose libraries with small dependency footprints
- your organization cannot accept the project's labor-law-related usage clause
- you need only one narrow feature and don't want a kitchen-sink library

## Facets
- artifact type: library
- maturity: active
- function: cryptography, serialization, compression, image-processing, concurrency, date-time, math, developer-tools, file-system, logging
- domain: developer-tools, cross-platform, files
