SHA256 Checksums & Signatures
Why verify
Every official release publishes SHA256 hashes and code-signing signatures. After you download, compute the hash locally and compare it to the published value before running the installer.
How to verify on Windows
- Open PowerShell in the folder containing the installer.
- Run the command below and wait for the hash output.
- Compare the output to the value listed for your file version.
Get-FileHash .\wireshark-setup.exe -Algorithm SHA256Per-file hashes
SHA256 values are unique per installer file and release version.
Compare your computed hash to the value listed alongside each download on this page. Mismatches mean the file was altered or corrupted—do not install until you confirm the source.
Security & Integrity
- Signed Windows and macOS binaries from the official build process
- Reproducible build practices and a public issue tracker for vulnerabilities
- No adware, spyware, or bundled malware in official installers
- Npcap is a separate signed component required for Windows capture
