Use this command to install OpenHashTab:
winget install --id=namazso.OpenHashTab -e OpenHashTab is a shell extension for conveniently calculating and checking file hashes from file properties.
OpenHashTab is a shell extension designed to streamline the process of calculating and verifying file hashes directly from the file properties menu in Windows. This tool simplifies hash operations by integrating seamlessly into the operating system’s context menu, enabling users to access essential hashing functionalities with just a few clicks.
Key Features:
- Support for multiple hashing algorithms, including SHA-1, SHA-256, and MD5.
- Integration into the right-click context menu for quick access.
- Drag-and-drop functionality to hash multiple files at once.
- The ability to compare hashes against known values for file integrity verification.
Audience & Benefit:
Ideal for IT professionals, security experts, developers, and anyone requiring fast and reliable file hashing operations. OpenHashTab enhances workflow efficiency by providing direct access to essential tools within the familiar Windows environment, eliminating the need for standalone applications or command-line interfaces.
Available via winget for easy installation, OpenHashTab is a lightweight yet powerful solution for managing file hashes with precision and convenience.

OpenHashTab
About
OpenHashTab is a shell extension for conveniently calculating and checking file hashes from file properties.
Features
- Support for 28 algorithms, see Algorithms
- High performance hash calculation
- Native Windows looks
- High DPI screen support
- Long path support*
- Multilingual (Consider contributing to translation!)
- Check hashes against VirusTotal with a button
- Hash checking against a checksum file (Supported: hex hash next to file, *sum output (hex or base64), corz .hash, SFV)
- Hash export to file or clipboard (Supported: *sum output, corz .hash, SFV)
- Optional context menu option for faster access
- File associations and standalone mode
* to the extent Windows and configuration supports it. Enable long paths on 1607+ for better support.
System requirements
- Windows 7 or later (x86 / x64 / ARM64)
- 1 GB RAM or more (for efficient hashing of more than 512 files at a time)
Usage
Most of the actions should be obvious. Some not-so-obvious features are listed here:
- You can select multiple files or folders, all files will be hashed, directories traversed
- Double click hash to copy it
- Double click name or algorithm to copy the line in sumfile format
- Right click for popup menu: copy hash, copy filename, copy line, copy everything
- The counters next to the status text is in the format
(match/mismatch/nothing to check against/error) - Columns sort lexicographically, except the hash column which sorts by match type
- Selecting the tab on a sumfile will interpret it as such and hash the files listed in it.
- If a hashed file has a sumfile with same filename plus one of the recognized sumfile extensions and the option for it is enabled, the file hash is checked against it.
Advanced features
Override Windows language selection
Add a DWORD named LangIdOverride to HKEY_CURRENT_USER\SOFTWARE\OpenHashTab with your preferred LCID
Disable VirusTotal button for all users on a machine
Add a DWORD named ForceDisableVT to HKEY_LOCAL_MACHINE\SOFTWARE\OpenHashTab with a nonzero value
