# OpenHashTab
[](COPYING) [](https://hosted.weblate.org/projects/openhashtab/main/) [](https://github.com/namazso/OpenHashTab/releases/latest) [](https://github.com/namazso/OpenHashTab/releases/latest) [](https://chocolatey.org/packages/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](https://www.tenforums.com/tutorials/51704-enable-disable-win32-long-paths-windows-10-a.html) 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](https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-lcid/70feba9f-294e-491e-b6eb-56532684c37f)
**Disable VirusTotal button for all users on a machine**
Add a `DWORD` named `ForceDisableVT` to `HKEY_LOCAL_MACHINE\SOFTWARE\OpenHashTab` with a nonzero value
## Algorithms
* CRC32, CRC64 (xz)
* xxHash (XXH32, XXH64)
* xxHash3 (64 and 128 bit variants)
* MD4, MD5
* RipeMD160
* Blake2sp
* SHA-1
* SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512)
* SHA-3 (SHA3-224, SHA3-256, SHA3-384, SHA3-512)
* BLAKE3 (256 bit, 512 bit)
* KangarooTwelve (264 bit, 256 bit, 512 bit)
* ParallelHash128 (264 bit) and ParallelHash256 (528 bit)
* Streebog (GOST R 34.11-12) (256 bit, 512 bit)
