Package aes
import "crypto/aes"
This package implements AES encryption (formerly Rijndael), as defined in U.S. Federal Information Processing Standards Publication 197.
Package files
block.go cipher.go const.goConstants
The AES block size in bytes.
const BlockSize = 16
type Cipher
A Cipher is an instance of AES encryption using a particular key.
type Cipher struct {
// contains unexported fields
}
func NewCipher
func NewCipher(key []byte) (*Cipher, os.Error)
NewCipher creates and returns a new Cipher. The key argument should be the AES key, either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
func (*Cipher) BlockSize
func (c *Cipher) BlockSize() int
BlockSize returns the AES block size, 16 bytes. It is necessary to satisfy the Cipher interface in the package "crypto/block".
func (*Cipher) Decrypt
func (c *Cipher) Decrypt(src, dst []byte)
Decrypt decrypts the 16-byte buffer src using the key k and stores the result in dst.
func (*Cipher) Encrypt
func (c *Cipher) Encrypt(src, dst []byte)
Encrypt encrypts the 16-byte buffer src using the key k and stores the result in dst. Note that for amounts of data larger than a block, it is not safe to just call Encrypt on successive blocks; instead, use an encryption mode like CBC (see crypto/block/cbc.go).
func (*Cipher) Reset
func (c *Cipher) Reset()
Reset zeros the key data, so that it will no longer appear in the process's memory.
type KeySizeError
type KeySizeError int
func (KeySizeError) String
func (k KeySizeError) String() string
