Downloads

These pages contain a set of tools and resources that can help you set up and use Horizon3 services.

Verify download authenticity

To ensure the integrity and authenticity of your files, always verify that downloads originate from Horizon3.ai.

Every download distributed here includes: - A download file (the actual tool or resource). - A checksum file containing a SHA256 hash to confirm the file’s authenticity and integrity.

Given the nature of cybersecurity, we strongly recommend verifying any file claiming to come from Horizon3.ai against the official checksums posted on this site.

Choose your operating system to view step-by-step instructions:

Linux

Ensure the downloaded image file and the sha256sum checksum file are in the same directory.

Run the following command in the directory:

sha256sum -c *.sha256.checksum

Sample output: 

nodezero@nodezero:~$ sha256sum -c *.sha256.checksum
NodeZero-1717717928.ova: OK
checkenv.sh: OK
nodezero@nodezero:~$

Note

Most Linux distributions come with a sha256sum command line utility that reads a checksum file, computes the checksum against the file it represents, and returns OK if they match.

MacOS

Ensure the downloaded image file and the sha256sum checksum file are in the same directory.

Run the following command:

shasum -c *.sha256.checksum
Sample output: 
horizon3@mac:~$ shasum -c *.sha256.checksum
NodeZero-1717717928.ova: OK
horizon3@mac:~$

Note

Most MacOS systems come with a utility called shasum that is a command line utility that reads a checksum file, computes the checksum against the file it represents, and returns OK if they match.

Windows

Ensure the downloaded image file and the sha256sum checksum file are in the same directory.

Run the following command:

Get-Content -Path .\*.sha256.checksum | % {$Hash, $_, $File = $_.Split(" ", 3); if ($Hash) { [PSCustomObject]@{Path=$File; Result=if ((Get-FileHash -Path $File -Algorithm SHA256).Hash -eq $Hash) { "OK" } else { "FAILED" }}}} | Format-List
Sample output: 
PS C:\Users\horizon3\Downloads> Get-Content -Path .\*.sha256.checksum | % {$Hash, $_, $File = $_.Split(" ", 3); if ($Hash) { [PSCustomObject]@{Path=$File; Result=if ((Get-FileHash -Path $File -Algorithm SHA256).Hash -eq $Hash) { "OK" } else { "FAILED" }}}} | Format-List


Path   : checkenv.sh
Result : OK

Path   : NodeZero-1717717928.ova
Result : OK

PS C:\Users\horizon3\Downloads>

Note

Windows Powershell has their own checksum utility.

Windows (manual)

This is an alternative way to verify the checksum file, you can run the following command:

more .\NodeZero-1717717928.ova.sha256.checksum; Get-FileHash .\NodeZero-1717717928.ova -Algorithm SHA256
Then manually compare the output with the contents of the checksum file yourself.

Sample output: 

PS C:\Users\horizon3\Downloads> more .\NodeZero-1717717928.ova.sha256.checksum; Get-FileHash .\NodeZero-1717717928.ova -Algorithm SHA256
