Hiew External Module (HEM) to calculate CRC-32, MD5, SHA-1, and SHA-256 hashes of files and blocks.
Extract the .hem file to Hiew's hem folder.
After opening a file in Hiew, press F11 to load a Hiew module and choose Hashes from the menu.
It will calculate common hashes of the whole file. For marked blocks, Hashes will generate
the hashes of the block content. Available commands:
F1show help window.F5copy selected hash to clipboard.F6copy all hashes to clipboard.ENTERcopy selected hash to clipboard and close Hashes window.
Hashes is fast. It calculates all four hash values it supports in the time it takes other software to calculate one. The following is a comparison table with other software hadhing a common 4 GB file. The hardware is also the same.

- Licensed version of Hiew.
- Windows Vista or newer.
- Visual C++ Redistributable for Visual Studio.
It is possible to use Hashes with it, but you need the following:
- Visual C++ Redistributable for Visual Studio v16.7. Download it from here (requires a Microsoft account).
bcrypt.dllin Hiew's folder or any other folder listed in%PATH%. There's an open source implementation here.
- @taviso for his kiewtai module (I borrowed code from it, but inserted my own bugs 🤠).
- SEN for Hiew.
