# Secret Scan

Catch a leaked credential before it lands in git history. No signup required.

## Prerequisites

- **None.** Pure Claude Code — works in any repo, no MCP required.

## Trigger

- "Scan for hardcoded secrets"
- "Any leaked keys in my changes?"
- "Secret scan before I commit"

## Workflow

1. Choose scope:
   - Pre-commit (default): `git diff` + `git diff --staged` — only what's about to land.
   - Full tree: scan tracked files (skip `.git`, `node_modules`, lockfiles, `dist/`, binaries).
2. Grep for these patterns (use `Grep`/ripgrep). Report matches with `file:line` and the value
   **masked** (show first 4 chars only) — never echo a full live secret.

### Patterns

| Provider / type     | Signature |
|---------------------|-----------|
| AWS access key      | `AKIA[0-9A-Z]{16}` |
| AWS secret key      | 40-char base64 near `aws_secret` |
| Google API key      | `AIza[0-9A-Za-z\-_]{35}` |
| GitHub token        | `ghp_`, `gho_`, `ghs_`, `github_pat_` |
| Slack token         | `xox[baprs]-` |
| Stripe              | `sk_live_`, `rk_live_` |
| OpenAI / Anthropic  | `sk-`, `sk-ant-` |
| Private key block   | `-----BEGIN (RSA |EC |OPENSSH |PGP )?PRIVATE KEY-----` |
| JWT                 | `eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\.` |
| Connection string   | `(postgres|mysql|mongodb(\+srv)?|redis)://[^ ]*:[^ @]*@` |
| Generic assignment  | `(password|passwd|secret|token|api[_-]?key)\s*[:=]\s*['"][^'"]{8,}` |

3. Triage each hit:
   - **Real secret** → BLOCKER. Recommend: remove, rotate the credential, move to env/secret store.
   - **Placeholder / example** (`your-key-here`, `xxxxx`, `${...}`, obvious test fixture) → note as ignored.
   - **In a committed file already in history** → flag that rotation is needed regardless of removal.

4. Output:

```
## Secret Scan — git diff (staged + unstaged)

**2 real secrets, 1 placeholder ignored**

### BLOCKER
- `backend/config.py:14` — Stripe live key `sk_l…` hardcoded.
  Rotate it now (it's compromised once committed) and load from env.
- `.env.example:9` — AWS key `AKIA…` looks real, not a sample.
  Move to a non-tracked `.env` and rotate.

### Ignored (placeholders)
- `README.md:42` — `api_key = "your-key-here"` — example text.
