Integrity Downloader

Integrity Downloader is a Windows application designed for downloading files from the Internet. The program uses multiple connections to increase transfer speed and performs integrity checks on downloaded data. It includes a built-in checksum verifier to validate files using MD5, SHA-1, SHA-256, and CRC32 algorithms. The interface offers download management with pause and resume options. It supports HTTP and HTTPS protocols and allows downloading of large files.

• Multi-part download. Integrity Downloader splits files into several segments that are downloaded simultaneously. This technique uses multiple parallel connections to the server, making better use of available bandwidth. Each segment is downloaded independently and then assembled into the final file, significantly reducing total transfer time.
• Integrity verification. The program implements automatic checksum verification after download completion. It calculates hash values of the obtained file using cryptographic algorithms and compares them with user-provided values. This feature ensures that data has not been corrupted during the transfer process.
• Resume downloads. Integrity Downloader can recover interrupted downloads from the point of failure. It saves transfer progress information in temporary files. If the connection is lost or the system shuts down, the program restarts the download where it left off, avoiding retransfer of already retrieved parts.
• Integrated hash checker. The tool includes a checksum validator with support for multiple algorithms. Users can manually verify the authenticity of any file by comparing its hash against a reference value. It supports MD5, SHA-1, SHA-256, and CRC-32 methods for compatibility with different standards.
• Connection customization. Allows adjusting the number of simultaneous connections per download. Users can configure this parameter according to their network capacity and remote server limitations. A higher number of connections can improve speed, while fewer connections may be necessary for servers with restrictions.
• Minimalist user interface. The application design focuses on essential functionalities without superfluous elements. It presents a clear layout with fields for URLs, action buttons, and progress area. Simplicity allows direct operation without requiring extensive learning.
• Activity log. Maintains a detailed log of events during the download process. The log includes information about established connections, transfer speeds, encountered errors, and completed operations. This data facilitates troubleshooting when issues occur.
• Browser integration. The software can capture download links from browser applications. When activated, it automatically detects download attempts and offers to manage them via Integrity Downloader. This feature simplifies the process of starting transfers.
• Adjustable speed limit. Allows setting restrictions on data transfer rate. Users can define maximum speed limits to prevent downloads from consuming all available bandwidth. This function is useful when needing to maintain capacity for other applications.
• Download manager. Provides an organized list of active and completed transfers. Each entry shows detailed information including URL, file size, progress, and current status. Users can manage multiple downloads simultaneously with individual controls to pause, resume, or remove.
• Proxy support. The application allows configuring proxy servers for network connections. It supports different types of proxies with optional authentication. This feature enables operation in restricted environments where direct Internet access is not available.

Integrity Downloader was developed by WinTools Software. The first version was released in 2016. The program is written in C++ and uses Windows libraries for its operation. Developers maintain regular updates to add compatibility with new web standards and improve performance. The application was specifically designed for Windows operating systems, leveraging native APIs to optimize network operations and file management.
