OpenHashTab

About

OpenHashTab is a shell extension for conveniently calculating and checking file hashes from file properties.

Features

• Support for 14 different selectable algorithms, see Algorithms
• md5sum / sha1sum / sha256sum / etc.. compatibility for checking and exporting hashes
• Easy to use checker and single-click sumfile export to clipboard or file
• Select then
• High performance hash calculation
• Native Windows looks
• Long path support*
• Multilingual: English, German, Italian, Hungarian, Simplified Chinese, Spanish, Danish, Russian

* On Windows 8 or later, to the extent Windows supports it.

System requirements

• Windows Vista or later (x86 / x64 / ARM64)
• 1 GB RAM or more (for efficent 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.
• Double click hash to copy it
• Double click name or algorithm to copy the line in sumfile format
• Select one or more lines then right click to copy all columns of the lines, separated by tabs
• Double right click to copy everything, separated by tabs
• The counters next to the status text is in the format (match/mismatch/nothing to check against/error)
• 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, the file hash is checked against it.

Algorithms

• CRC32
• MD2, MD4, MD5
• RipeMD160
• Blake2sp
• SHA-1
• SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512)
• SHA-3 (SHA3-256, SHA3-384, SHA3-512)
• BLAKE3
