🔐 Pribado

Private API Key Management & Zero-Knowledge Infrastructure

Pribado is a self-hostable, zero-knowledge platform for managing API keys, encrypted secrets, and private communications. Built on Oasis Sapphire for hardware-backed confidential computing.

---

✨ Features

🔑 Private API Proxy

• Store API keys (OpenAI, Anthropic, Google, etc.) encrypted
• Generate proxy keys (priv_xxx) to use instead of exposing real keys
• Automatic key rotation with webhook notifications
• Zero-knowledge: server stores encrypted blobs it cannot decrypt

🗄️ Encrypted Vault

• Password manager with AES-256-GCM encryption
• Keys derived from your wallet signature (never stored)
• Backup to Oasis Sapphire blockchain
• Cross-device sync via encrypted chain storage

💬 Anonymous Chat

• End-to-end encrypted real-time messaging
• No accounts, no identity tracking
• Messages exist only in transit (not stored)
• Ephemeral session keys

📄 Document Signing

• Sign PDFs with digital signatures
• Anchor document hashes to Sapphire blockchain
• Immutable proof of existence and integrity

🛡️ Security Architecture

• Double-layer encryption: Wallet-derived keys + server enclave
• Hardware TEE: Oasis Sapphire confidential smart contracts
• Zero-knowledge: Server cannot read your data
• Rate limiting: IP-based spam/abuse protection

🚀 Quick Start

Prerequisites

• Node.js v20+
• npm v10+

Installation

# Clone the repository
git clone https://github.com/0xrlawrence/Pribado.git
cd Pribado

# Install dependencies
npm install

# Create environment file
cp .env.local.example .env.local

# Generate encryption secret
echo "ENCLAVE_SECRET=$(openssl rand -hex 32)" >> .env.local

# Build and run
npm run build
npm start

Open http://localhost:3000 in your browser.

Docker

docker-compose up -d

---

🔧 Configuration

Variable	Description	Required
ENCLAVE_SECRET	64-char hex encryption key	✅ Yes
SAPPHIRE_PRIVATE_KEY	Oasis wallet private key	❌ Optional
SAPPHIRE_RPC_URL	Oasis RPC endpoint	❌ Optional

See SELF_HOSTING.md for complete deployment guide.

📦 CLI Tool

Manage API keys from the command line:

# Install globally
npm install -g pribado-cli

# Or use npx
npx pribado-cli

# Set up wallet
pribado init

# Add an API key
pribado keys add

# View your keys
pribado keys

# Revoke a key
pribado keys revoke

See cli/README.md for full documentation.

🔐 Security

Pribado implements a zero-knowledge architecture:

User's Wallet Signature
        ↓
PBKDF2 (100,000 iterations)
        ↓
Encryption Key (exists ONLY in browser memory)
        ↓
AES-256-GCM Encryption
        ↓
Encrypted blob sent to server

Result: Server stores encrypted data it CANNOT decrypt.

For detailed security documentation, see SECURITY.md.
