Verify a package

To check file integrity, download the SHA-256 checksum file next to the package link. The checksum file contains the package's SHA-256 checksum and filename.

Open a terminal in the download directory and replace <package-name> with the downloaded filename. Calculate the package's SHA-256 checksum with the command for your operating system:

LinuxmacOSWindows PowerShell

sha256sum "<package-name>"

shasum -a 256 "<package-name>"

Get-FileHash -Algorithm SHA256 -Path "<package-name>"

The calculated checksum must match the value in the checksum file; letter case does not matter. If the values differ, download the package again and repeat the check.
