Installer Verification

How to verify your installation of Nova Spektr!

When you download an installation of Nova Spektr from the official website or GitHub, checking the file checksum provides a way to confirm that the file you received is identical to the one that was originally uploaded to the official website or GitHub.

This is important for several reasons:

Data integrity

By comparing the checksum of the downloaded file with the provided checksum value, you can ensure that the file has not been tampered with or modified. Even small changes to a file can have significant consequences, such as introducing malware or compromising the functionality of Nova Spektr.

Data transmission errors

During the process of downloading a file, errors can occur that result in data corruption. Checking the file checksum allows you to detect such errors and identify whether the downloaded file is complete and accurate. If the checksum does not match, it indicates that the file is not identical to the original one, and you may need to re-download it.

Authenticity verification

Verifying the file checksum can help you confirm the authenticity of the file. It helps prevent the installation of malicious or modified versions of Nova Spektr.
