- Implements end-to-end encryption (E2EE) utilities for secure A2A (Agent-to-Agent) communication.

# A2A End-to-End Encryption
Provides encryption utilities for secure agent-to-agent communication.
## Features
- **Key Generation**: RSA key pair generation for asymmetric encryption
- **Message Encryption**: Encrypt messages with recipient's public key
- **Message Decryption**: Decrypt messages with own private key
- **Key Exchange**: Secure key exchange protocols
- **Key Rotation**: Automatic key rotation support
- **Message Integrity**: HMAC-based message authentication
## Usage
```javascript
const e2ee = require('./skills/a2a-e2ee-encryption');
// Generate key pair
const keyPair = e2ee.generateKeyPair();
// Encrypt message
const encrypted = e2ee.encrypt('secret message', recipientPublicKey);
// Decrypt message
const decrypted = e2ee.decrypt(encrypted, privateKey);
// Export/Import keys
const exported = e2ee.exportKey(keyPair.publicKey);
const imported = e2ee.importKey(exported);
```
## Architecture
```
┌─────────────┐ ┌─────────────┐
│ Agent A │ │ Agent B │
│ │ │ │
│ Private Key │ │ Private Key │
│ Public Key │◄──── Exchange ────►│ Public Key │
│ │ │ │
│ Encrypt │──── Encrypted ────►│ Decrypt │
│ with B's │ Message │ with A's │
│ Public Key │ │ Public Key │
└─────────────┘ └─────────────┘
```
## Security Considerations
1. **Key Storage**: Private keys should be stored securely (env vars, vault)
2. **Key Rotation**: Rotate keys periodically for forward secrecy
3. **Key Validation**: Always verify key fingerprints before use
4. **Message Size**: Large messages should use hybrid encryption
