//! AES ECB, CBC, XTS, CTR, CFB, GCM and other conventional symmetric encryption

//! create a new key with [`new_encrypt`] and perform an encryption/decryption

//! using that key with [`aes_ige`].

//! The [`symm`] module should be used in preference to this module in most cases.

//! The IGE block cypher is a non-traditional cipher mode.  More traditional AES

//! encryption methods are found in the [`Crypter`] and [`Cipher`] structs.
