About

Command-line utility for creating or verifying checksums using fast non-cryptographic algorithm xxHash.

xxHash is an Extremely fast Hash algorithm, processing at RAM speed limits. Code is highly portable, and produces hashes identical across all platforms (little / big endian). The library includes the following algorithms:

- XXH32: generates 32-bit hashes, using 32-bit arithmetic

- XXH64: generates 64-bit hashes, using 64-bit arithmetic

- XXH3 (since v0.8.0): generates 64 or 128-bit hashes, using vectorized arithmetic. The 128-bit variant is called XXH128.

All variants successfully complete the SMHasher test suite which evaluates the quality of hash functions (collision, dispersion and randomness). Additional tests, which evaluate more thoroughly speed and collision properties of 64-bit hashes, are also provided.

Security

No known CVEs for xxhsum.

Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.

Frequently asked questions

How do I install xxhsum on Windows?
Open Windows Terminal, PowerShell, or Command Prompt and run: winget install --id Cyan4973.xxhsum --exact --version 0.8.3. winget downloads the installer from Cyan4973 and runs it. Requires Windows 10 (1809+) or Windows 11.
How do I install xxhsum silently for unattended deployment?
Add --silent and accept the agreements upfront: winget install --id Cyan4973.xxhsum --exact 0.8.3 --silent --accept-package-agreements --accept-source-agreements. This is the variant Intune, Configuration Manager, and other deployment tools should use.
How do I uninstall xxhsum via winget?
Run: winget uninstall --id Cyan4973.xxhsum --exact. Add --silent for unattended uninstalls. winget will use the registered uninstaller from xxhsum's Apps & Features entry.
Is xxhsum free?
xxhsum is distributed under BSD-2-Clause. Refer to the publisher (https://xxhash.com/) for the full license terms - Wingetly itself does not charge for installation.
Does xxhsum work on Windows 10?
Yes, as long as your Windows 10 build supports winget (1809 or newer). winget ships with App Installer on Windows 10/11 and pulls xxhsum directly from the publisher.
How do I keep xxhsum up to date?
Run winget upgrade --id Cyan4973.xxhsum --exact, or winget upgrade --all to update everything winget tracks. We index 1 version of xxhsum from microsoft/winget-pkgs.
