Verify

Before start using the GUI, it's strongly recommended to verify the authenticity of the krux-installer.SHA256.txt file. It attest the integrity of all variants (krux_installer_0.0.21_amd64.deb, krux_installer-0.0.21-1.x86_64.rpm, krux_installer_0.0.21_arm64.dmg, krux_installer_v0.0.21_Setup.exe).

To do this, download two files:

• krux-installer.SHA256.txt;
• krux-installer.SHA256.txt.sig.

Verify the authenticity

Linux/MacOS

The next step is import the developer's key:

gpg --keyserver hkps://keys.openpgp.org --recv-keys B4281DDDFBBD207BFA4113138974C90299326322

Then, to verify yourself, run this:

gpg --verify krux-installer.SHA256.txt.sig

Windows

• You'll need have GPG installed;
• We recommend installing GPG4Win.

After install, you can proceed with Linux/MacOS steps in the terminal.

⚠️ TIP: If the verification was successful, you may get a message similar to: Good signature from "qlrddev <qlrddev@gmail.com>". Also, you can ignore a WARNING message if it says that the key isn't a trusted one (you need to do it manually).

Verify the integrity

After verify that the krux-installer.SHA256.txt is authentic, we can proceed with the integrity check in your bash/zsh terminal:

Linux / MacOS

sha256sum --check krux-installer.SHA256.txt

Windows

You can verify the integrity with this command in a powershell terminal:

$exe = '.\krux_installer_v0.0.21_Setup.exe'
$file = Split-Path $exe -Leaf

(Get-FileHash $exe -Algorithm SHA256).Hash -eq
(Select-String $file '.\krux-installer.SHA256.txt').Line.Split()[0].ToUpper()

🛡️ TIP: If you followed the authenticity/integrity checks steps presented, you already have the assurance that the software is from a verified and genuine software publisher. This will also help establish a chain of trust when you perform the firmware verification step before flashing.
