It is important to download Arch Linux from a trusted sources. > Always check the download against signatures and checksums published on the official > [Arch Linux][arch-linux-sources] website. Do not trust signatures published by download > mirrors or 3rd party websites, as they could be tampered with. ## Checksum Verification ### Using GnuPG To verify the PGP signature with GnuPG, first download the release signing key from [WKD (Web Key Discovery)][wkd] or any key service that you trust. ```sh gpg --auto-key-locate clear,wkd -v \ --locate-external-key pierre@archlinux.org ``` Then use the obtained key to verify the signature of the downloaded file ```sh gpg --keyserver-options auto-key-retrieve \ --verify archlinux-.iso.sig ``` ### Using an existing Arch Linux System On a system already running Arch Linux, `pacman` can be used to verify the Installation Medium. ```sh pacman-key -v archlinux-.iso.sig ``` ## Create a Bootable Medium Create a bottable medium from the downloaded **and verified** Arch Linux ISO. For example, a bootable USB flash drive. Execute the following command to copy the downloaded ISO to the USB flash drive. > Important: The following command will permanently delete the data of the destination device. > Make sure to specify the correct destination device and to back up important data prior to executing > this command. ```sh dd bs=4M \ if= \ of=/dev/disk/by-id/usb- \ conv=fsync oflag=direct status=progress ``` > Tip: After you are done using the USB flash drive for the Arch Linux installation, the following > command must be executed to delete the ISO 9660 filesystem signature from the device to use it > as a normal USB flash drive again. > > ```sh > wipefs --all /dev/disk/by-id/usb- > ``` For more details, see [Arch Linux Wiki: USB Flash Installation Medium][arch-wiki-usb-install].
