File Hash Calculator

File Hash Calculator is a small Windows utility that can calculate and compare file hash sums. The following algorithms are supported:

• MD5
• SHA1
• SHA256
• SHA512

Requirements

File Hash Calculator requires .NET Framework 4.6.1 - this is supported on Windows 7 (SP1) and upwards.

Installation

Pre-built binaries are available on the Releases page.

Alternatively, you can build your own binaries from source if you prefer. Once built, the following files are required for correct operation:

• HashCalculator.exe
• Ninject.dll

Features

1. Can generate hash sums using MD5, SHA1, SHA256, and SHA512 algorithms

2. Easy to use: simply drag and drop to add files. Known hash sums can optionally be added for comparison, with visual feedback

3. Small footprint: the files required for operation total approximately 260 KB

Usage

• Drag files from Windows File Explorer and drop them onto the Input Files area

• Edit the file Path if needed for different files. The cell background will change colour if the file path is invalid.

• Remove files by either deleting the entire path, or by clicking on the button in the right-most column

• Select the algorithm to use in the drop-down box near the bottom of the app window

• Optionally enter known hash sums that should match the calculated hash sums in the format

  HashSum *FileName/FilePath

• Click Calculate

• The hash sums and file names/paths will be checked for matches. To match files using the filename and extension only, leave Full Path unselected; to match using the full file path, select Full Path

• While computing the hash sums of multiple files, it is possible to stop the process after the computation of the current in-progress file by clicking Cancel

• To export the calculated hash sums to a file for future reference, click Export
