File Hash Generator & Validator

MVVM application structure

The application follows a lightweight MVVM structure, separating the WPF interface from the application's state and command handling.

Dedicated hashing service

File hashing is exposed through a dedicated FileHashService rather than being embedded directly into the view layer. The service integrates the KZ.FileHash engine.

Core application components

The project contains dedicated models, services, view models, commands, and converters, keeping the desktop application structure lightweight and explicit.

Local asynchronous processing

File operations are performed asynchronously with cancellation and progress reporting, allowing the application to handle large files without tying the UI directly to synchronous processing.

Incremental processing

The application does not load complete files into system memory before hashing. File data is processed incrementally through buffered streaming.

Low and predictable memory usage

KZ.FileHash processes data in buffered chunks and uses pooled memory internally, keeping allocations low relative to the size of the file being processed.

Large-file testing

The project successful processing of files larger than 3 GB without memory spikes or UI freezing.
