Checksums and signatures

Keep the executable and its .sha256 file in the same folder. A match prints OK.

# Linux
sha256sum -c lispex-linux-x86_64.sha256

# macOS
shasum -a 256 -c lispex-macos-aarch64.sha256

In Windows PowerShell, a match prints True.

(Get-FileHash .\lispex-windows-x86_64.exe).Hash -eq $want

What a download check establishes

A checksum identifies the exact bytes you downloaded.

Signed distribution and the recipient's trust policy identify the publisher and the accepted source.

Lispex Vouch records the current decision, and the receiving application authorizes any external action.

Run directly on Windows

Keep hello.lspx in the same folder as the executable.

.\lispex-windows-x86_64.exe hello.lspx
