### NewWithManualNonces

Source: https://pkg.go.dev/filippo.io/xaes256gcm

Documentation for the NewWithManualNonces function, which creates an XAES-256-GCM AEAD instance with manual nonce management.

```APIDOC
## NewWithManualNonces(key []byte) (cipher.AEAD, error)

### Description
Returns a new XAES-256-GCM instance that expects 24-byte nonces to be passed to Open and Seal. Nonces can be safely generated with crypto/rand.Read. The key must be exactly 32 bytes long.

### Function Signature
func NewWithManualNonces(key []byte) (cipher.AEAD, error)

### Parameters
- **key** ([]byte) - Required - The encryption key, must be exactly 32 bytes long.

### Returns
- **cipher.AEAD** - The AEAD instance for encryption/decryption.
- **error** - An error if the key length is invalid.

### Usage Notes
Most applications should use New instead, which automatically generates random nonces and prepends them to the ciphertext. (Note that New is not implemented yet.)
