diff4 encrypts diffs and files client-side (AES-256-GCM) before uploading. The server never sees plaintext. Recipients need the passphrase to decrypt.
diff4 must be installed and available on PATH. Use npm i -g @diff4/cli to install.diff4 git-latest
Runs git diff HEAD~1, encrypts the result, and uploads. Use when the user says "preview my last commit" or "send the latest diff."
diff4 git-staged
Runs git diff --staged, encrypts, and uploads. Use when the user says "preview my staged changes" or "send what's about to be committed."
diff4 files path/to/file1.ts path/to/file2.ts
Reads each file (UTF-8 text only), bundles them as JSON, encrypts, and uploads. Supports any number of paths (relative or absolute).
diff4 key-gen [key] - Generate or set the encryption passphrasediff4 key-get - Print the current passphraseAll upload commands (git-latest, git-staged, files) accept:
| Flag | Description |
|---|---|
-s, --server <url> | Override the diff4 server URL. Default: https://diff4.com (or DIFF4_SERVER env var) |
-p, --passphrase <key> | Override the passphrase for this command only. Default: DIFF4_PASSPHRASE env var |
git-latest and git-staged will error if there is nothing to share.diff4 files reads files as UTF-8 text.DIFF4_SERVER env var or -s flag.DIFF4_PASSPHRASE already exists in the shell config, key-gen replaces it in-place.diff4 key-get (if it fails, run diff4 key-gen and tell user to source their rc file)git-latest, git-staged, or files <paths>)
