• Gnoppix Beta Images
• Gnoppix Member Server

Verifying ISO integrity with SHA256

WARNING

Always take an extra step to verify the ISOs integrity to avoid any undesired issues at installation or while creating a bootable media.

Current ISO Version: 250204

SHA256 Hash: 6b6562602705da3228d9862d7016a00ca6fa482482b87fd15656f9b2793f4ef6

Windows

1. Download the file containing the SHA256 hash (Open it with a Text Editor e.g: Notepad).
2. Open CMD or PowerShell as Administrator and navigate to the path where the ISO and SHA256 files are stored.
3. Execute the following command:

   # Example:
   certUtil -hashfile gnoppix-desktop-linux-241221.iso SHA256

4. Compare the certUtil hash output to the one from the downloaded file in Step 1. If they match, you can proceed with the Gnoppix installation.

Linux

1. Download the file containing the SHA256 hash.
2. Open a terminal and navigate to the directory containing the .sha256 file and execute the following commands:

   # Example:
   cd Downloads/
   cat gnoppix-desktop-linux-241221.iso.sha256
   # 6b6562602705da3228d9862d7016a00ca6fa482482b87fd15656f9b2793f4ef6

3. Compare the output from Step 2 and execute the following command to check what’s the current hash in the ISO file.

   # Example:
   sha256sum gnoppix-desktop-linux-241221.iso

4. If the hashes from Step 2 and Step 3 match, you can proceed with the Gnoppix installation.

macOS

1. Download the file containing the SHA256 hash.
2. Open a terminal and navigate to the directory containing the .sha256 file and execute the following commands:

   # Example:
   cd Downloads/
   cat gnoppix-desktop-linux-241221.iso.sha256
   # 6b6562602705da3228d9862d7016a00ca6fa482482b87fd15656f9b2793f4ef6

3. Compare the output from Step 2 and execute the following command to check what’s the current hash in the ISO file.

   # Example:
   shasum -a 256 gnoppix-desktop-linux-241221.iso

4. If the hashes from Step 2 and Step 3 match, you can proceed with the Gnoppix installation.

Verify ISO Image Authenticity (Linux)

To verify the authenticity of the ISO file to be sure that the actual one has been released by the official Gnoppix development team:

1. Import the GPG key for verifying the authenticity:

   gpg --keyserver hkps://keys.openpgp.org --recv-key EA04DED48A72B3780909169E8F0C4802B19DD03E

2. Download the ISO file and its .sig signature file and run the following command (by replacing full_iso_name.iso with the actual ISO filename):

   gpg --verify full_iso_name.iso.sig full_iso_name.iso

   If you get a Good signature output, the ISO file is genuine:

   pub   rsa4096 2024-11-10 [SC] [expires: 2034-11-08]
      EA04 DED4 8A72 B378 0909  169E 8F0C 4802 B19D D03E
   uid           [ultimate] Andreas Mueller <[email protected]>
   sub   rsa4096 2024-11-10 [E] [expires: 2034-11-08]

Danger

If the output does not return Good signature string or the key ID does not match, don’t use the ISO image and make sure that the downloaded image comes from a legitimate Gnoppix source. A bad signature could suggest that the downloaded image has been tampered with.
