		```javascript
		const XChaCha20 = require('xchacha20-js');

		let xcha20 = new XChaCha20;
		let message = "test message";
		let key = Buffer.from('808182838485868788898a8b8c8d8e8f909192939495969798999a9b9c9d9e9f', 'hex');

		let blockCounter = 1; // Optional, defaults to 1 per the RFC
		let ciphertext = xcha20.encrypt(message, nonce, key, blockCounter);
		let plaintext = xcha20.decrypt(ciphertext, nonce, key, blockCounter);
