BlackVault — Proxy gateway for AI API keys

What it does

When you share an API key with an AI agent, you cannot revoke just that agent access without rotating the key. BlackVault fixes this with a proxy layer:

Agent → BlackVault (proxy token) → OpenAI/Anthropic/Google (real key)

The agent never sees the real API key. Kill the proxy token = instant 401.

Features

• AES-256-GCM encrypted vault with per-user derived keys
• Proxy gateway with full SSE streaming (OpenAI, Anthropic, Google AI)
• Instant kill switch — revoke per-session, per-key, or everything
• Per-session cost tracking with model-level accuracy
• Activity audit trail
• Self-hostable, open source, free
