# CIFER SDK - Quantum-Resistant Blockchain Encryption

> **Skill for AI Agents** | Enable quantum-resistant encryption in blockchain applications using the CIFER SDK.

## Overview

CIFER (Cryptographic Infrastructure for Encrypted Records) SDK provides quantum-resistant encryption for blockchain applications. This skill enables AI agents to implement secure data encryption, secret management, and on-chain commitments using post-quantum cryptography.

### Key Capabilities

- **Quantum-Resistant Encryption**: ML-KEM-768 (NIST standardized) key encapsulation
- **Multi-Chain Support**: Automatic chain discovery and configuration
- **Wallet Agnostic**: Works with MetaMask, WalletConnect, Coinbase, Thirdweb, and custom signers
- **File Encryption**: Async job system for large file encryption/decryption
- **On-Chain Commitments**: Store encrypted data references on-chain with log-based retrieval
- **Transaction Intents**: Non-custodial pattern - you control transaction execution

## When to Use This Skill

Use the CIFER SDK when you need to:

- Encrypt sensitive data with quantum-resistant algorithms
- Store encrypted records on blockchain
- Manage encryption keys with owner/delegate authorization
- Encrypt files larger than 16KB using the job system
- Build applications requiring post-quantum security

## Installation

```bash
npm install cifer-sdk
# or
yarn add cifer-sdk
# or
pnpm add cifer-sdk
```

**Requirements**: Node.js 18.0+, TypeScript 5.0+ (recommended)

## Quick Start

```typescript
import { createCiferSdk, Eip1193SignerAdapter, blackbox } from 'cifer-sdk';

// 1. Initialize SDK with auto-discovery
const sdk = await createCiferSdk({
  blackboxUrl: 'https://blackbox.cifer.network',
});

// 2. Connect wallet (browser)
const signer = new Eip1193SignerAdapter(window.ethereum);

// 3. Encrypt data
const encrypted = await blackbox.payload.encryptPayload({
  chainId: 752025,
  secretId: 123n,
  plaintext: 'My secret message',
  signer,
  readClient: sdk.readClient,
