-/// Represents the state of an AEAD cipher when using [`Aes256Gcm`], including the encryption key
-/// and nonce.
-///
-/// The [`Cipher`] struct manages the cryptographic state required to perform AEAD encryption and
-/// decryption operations. It stores the optional 32-byte encryption key (`k`), the nonce (`n`),
-/// and the optional cipher instance itself. The [`CipherState`] trait is implemented for this
-/// struct to provide a consistent interface for managing cipher state across different AEAD
-/// ciphers.
