Every release ships a checksums.txt with a SHA‑256 hash for each file. Check your download against it to confirm the bytes are exactly what we published — not corrupted, not tampered with.
checksums.txt from the latest release.shasum -a 256 -c checksums.txt
Reports OK for each file it finds. Lines for files you did not download show as missing — that is normal.
sha256sum -c checksums.txt
No sha256sum? shasum -a 256 -c checksums.txt works too.
Get-FileHash .\Jumpgate-windows-amd64.zip -Algorithm SHA256
Compare the printed Hash to the matching line in checksums.txt (case does not matter). Swap in your file name.
A match. On macOS and Linux that reads:
Jumpgate-macos-arm64.zip: OK
If a file reports FAILED, or a Windows hash does not match, do not run it. Download it again, and if it still fails, open an issue.
