| Summary : Crypt::CBC compliant Rijndael encryption module
|
Description :
This module implements the Rijndael cipher, which has just been selected as
the Advanced Encryption Standard.
* keysize
Returns the keysize, which is 32 (bytes). The Rijndael cipher actually
supports keylengths of 16, 24 or 32 bytes, but there is no way to
communicate this to \'Crypt::CBC\'.
* blocksize
The blocksize for Rijndael is 16 bytes (128 bits), although the algorithm
actually supports any blocksize that is any multiple of our bytes. 128
bits, is however, the AES-specified block size, so this is all we support.
* $cipher = Crypt::Rijndael->new( $key [, $mode] )
Create a new \'Crypt::Rijndael\' cipher object with the given key (which must
be 128, 192 or 256 bits long). The additional \'$mode\' argument is the
encryption mode, either \'MODE_ECB\' (electronic codebook mode, the default),
\'MODE_CBC\' (cipher block chaining, the same that \'Crypt::CBC\' does),
\'MODE_CFB\' (128-bit cipher feedback), \'MODE_OFB\' (128-bit output feedback),
or \'MODE_CTR\' (counter mode).
ECB mode is very insecure (read a book on cryptography if you don\'t know
why!), so you should probably use CBC mode.
* $cipher->set_iv($iv)
This allows you to change the initial value vector used by the chaining
modes. It is not relevant for ECB mode.
* $cipher->encrypt($data)
Encrypt data. The size of \'$data\' must be a multiple of \'blocksize\' (16
bytes), otherwise this function will croak. Apart from that, it can be of
(almost) any length.
* $cipher->decrypt($data)
Decrypts \'$data\'.
