Verify the download

Checking the hash is optional. It tells you whether the file on your disk is the one that was published.

Windows#

Open PowerShell in the folder with the file:

Get-FileHash .\FireClient-Setup.exe -Algorithm SHA256

macOS and Linux#

shasum -a 256 FireClient-macOS-universal.dmg
sha256sum FireClient-Linux-x86_64.AppImage

Compare#

Match the result with the SHA-256 shown on the download page. The page only shows one when GitHub publishes it.

What a match means#

A match means the file is the one that was published. It does not prove the file is free of malware. Scan it with your usual security tool if you want another opinion.

The launcher's updater also checks SHA-256 hashes when it installs updates.
