Package aes implements AES encryption (formerly Rijndael), as defined in
U.S. Federal Information Processing Standards Publication 197.
The AES operations in this package are not implemented using constant-time algorithms.
An exception is when running on systems with enabled hardware support for AES
that makes these operations constant-time. Examples include amd64 systems using AES-NI
extensions and s390x systems using Message-Security-Assist extensions.
On such systems, when the result of NewCipher is passed to cipher.NewGCM,
the GHASH operation used by GCM is also constant-time.

Package-Level Functions (only one)
NewCipher creates and returns a new [cipher.Block].
The key argument should be the AES key,
either 16, 24, or 32 bytes to select
AES-128, AES-192, or AES-256.
Package-Level Constants (only one)
The AES block size in bytes.
