Verify a Codex theme SHA-256 checksum

Confirm that wallpaper, recipe, and token files match the transparent package manifest before use.

What the site hashes

A package v1 ZIP contains a wallpaper, theme.json and recipe.json, manifest.json, theme-tokens.css, readable install/restore/verify notes, README.md, and SHA256SUMS. The checksum list covers every payload, including the manifest and instruction files. The package contains no executable or installer; hashing helps detect accidental corruption or replacement after generation.

Verify on macOS or Linux

Open Terminal in the extracted directory. On macOS run shasum -a 256 -c SHA256SUMS; on Linux run sha256sum -c SHA256SUMS. Every row must pass. A single different character means the file is not identical and should not be assumed safe or complete.

Verify on Windows

Use Get-FileHash with -Algorithm SHA256 for each file and compare the Hash field. Checksums establish file identity, not author trust: a malicious publisher can hash a malicious file. Combine checksums with an original source, readable contents, and a known review process.

Checksums do not make executable code safe. `codextheme.tools` packages are intentionally data-only.
