Checking it yourself

On macOS or Linux, run shasum -a 256 <file>; on Windows, certutil -hashfile <file> SHA256. The output must match the line above character for character. Every archive also carries its own CHECKSUMS.sha256 covering each file inside it.

If a hash does not match, do not run the contents. Write to dev@KESJr.com and we will re-issue.

Sealed editions, hashed, checked against the same root of trust.

Each release is recorded with its hash so a copy either matches the sealed edition or it does not. Verification is arithmetic, not assurance.
