package aes

import "crypto/aes"

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.

Constants

const BlockSize = 16

The AES block size in bytes.

func NewCipher
¶

func NewCipher(key []byte) (cipher.Block, error)

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.

type KeySizeError
¶

type KeySizeError int

func (KeySizeError) Error
¶

func (k KeySizeError) Error() string
