Overview

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.
