# Generate Key

Generates a cryptographically secure 256-bit (32-byte) encryption key suitable for creating encrypted indexes.

```python theme={null}
@staticmethod
generate_key() -> bytes
```

### Returns

`bytes`: A 32-byte object containing cryptographically secure random data suitable for index encryption.

### Security Notes

The generated key is cryptographically secure and suitable for production use:

* Uses Python's `secrets.token_bytes()` which leverages OS entropy sources for maximum security
* Provides 256 bits of entropy (32 bytes)
* Compatible with AES-256 encryption used by CyborgDB

<Warning>
  This key must be persisted securely. For more information, see [Managing Encryption Keys](../../guides/advanced/managing-keys).
</Warning>

### Example Usage

```python theme={null}
from cyborgdb import Client

client = Client(base_url='http://localhost:8000', api_key='your-api-key')

# Generate a secure encryption key
index_key = client.generate_key()
print(f'Generated key length: {len(index_key)}')  # Output: 32

index = client.create_index(
    'my-secure-index',
    index_key,
)

# IMPORTANT: Store the key securely for future access
# key_hex = index_key.hex()
# print(f'Store this key safely: {key_hex}')
```
