In order to ensure that an installation media, installation image or installation file (patch image) really are genuine or were not corrupted during download, there is the possibility to verify the integrity with checksums.

Verification of checksums
On Unix systems, the integrity of the image can be verified by checksums as described below:
- Get the checksum from genua's web server.
- With the command corresponding to the type of the checksum, the local checksum is generated. Using OpenBSD as follows:
- openssl dgst -sha256 <FILE>
- openssl dgst -sha512 <FILE>
- Verify the checksums: Now compare the local checksum of the installation image in question with the checksum from genua's server. If the checksums match, the integrity of the image is verified. In case of differences, the support can assist you.
On some Linux systems (e. g. Debian), the corresponding commands for checksum generation are possibly named a little different: sha256sum, sha512sum.
On Windows 10 and Windows 11 the checksum can be generated with on-board tools on the CLI. Use the command:
"CertUtil -hashfile <path\to\file> SHA256"
