## 🛡️ ViBo Proxy — use ANY LLM, keep your secrets yours

Every prompt you send to an LLM (DeepSeek, OpenAI, Claude…) goes to the
provider's servers — including the API keys, passwords and customer data
that might be sitting in your context. ViBo Proxy is a privacy layer that
sits between your agent and the LLM:

```
Your agent ──► ViBo Proxy ──► any LLM
                 │
                 ├─ AES-256-GCM: secrets encrypted at rest
                 ├─ 🔒[name]: secrets masked before they leave your machine
                 └─ audit: every response shows what was blocked & saved
```

**What you get**

- **Secrets never reach the LLM.** Register a key once — it's stored
  encrypted (ciphertext only) and sent out as `🔒[name]`. Verified on a
  live test: the model echoed back `🔒[test_api_key]`, not the real value.
- **Any LLM, zero rewiring.** OpenAI-compatible (`/v1/chat/completions`),
  works with DeepSeek, OpenAI, and any agent with a configurable `base_url`.
  Streaming (SSE) supported.
- **Audit in every answer.** `vibo.secrets_blocked` + `vibo.tokens_saved` —
  you see what was protected and what it saved you.
- **Self-hosted in one command.** `UPSTREAM_API_KEY=*** bash setup.sh` →
  `http://localhost:8017/v1`. Or use the hosted endpoint `https://wwwvibo.com/v1`.

**Honest limits** (we don't oversell)

- Masked: registered secrets + known key/password patterns (`sk-…`,
  `ghp_…`, `password=…`).
- Not masked: the rest of the prompt — the LLM must read it to answer.
- Key location: on the proxy server by default; self-hosted = under your
  control. Zero-knowledge (client-side key) = client-side variant.

**One command to start:**

```bash
UPSTREAM_API_KEY=*** bash setup.sh        # builds + runs on :8017
curl http://localhost:8017/health         # → {"ok":true}
```
