> Your first Voltaire example - hashing a simple string with Keccak256

Your first Voltaire example - hashing a simple string with Keccak256

```typescript theme={null}
import { Keccak256 } from '@tevm/voltaire/Keccak256';
import { Hex } from '@tevm/voltaire/Hex';

// Hash a string using Keccak256
const hash = Keccak256("Hello, Voltaire!");

// The hash is returned as a Uint8Array - convert to hex
const hexHash = Hex.fromBytes(hash);
```
