SHA-256:
Windows SmartScreen note: this installer is signed by Nyx Software, LLC, so there is no "Unknown publisher" warning. A brand-new release can still show a blue "Windows protected your PC" screen until Microsoft SmartScreen builds reputation for it. If you see it, click More info, then Run anyway. To be sure the file is genuine, match its SHA-256 against the value shown above.
All downloads (version ...)
Every installer is code-signed for its platform (Authenticode on Windows, a
signed .pkg on macOS). Each release folder also carries
SHA256SUMS-<version>.txt listing every file's SHA-256, plus a
detached OpenPGP signature SHA256SUMS-<version>.txt.asc from the
Nyx Backup release key. To verify a download:
curl -s https://nyxbackup.com/keys/release.asc | gpg --import
gpg --verify SHA256SUMS-<version>.txt.asc SHA256SUMS-<version>.txt
sha256sum -c SHA256SUMS-<version>.txt # run in the folder with your download
