GOST(3) User Contributed Perl Documentation GOST(3)NAMECrypt::GOST - The GOST Encryption Algorithm
SYNOPSIS
use Crypt::GOST;
$cipher = Crypt::GOST->new($key);
$ciphertext = $cipher->encrypt($plaintext);
$plaintext = $cipher->decrypt($ciphertext);
DESCRIPTION
GOST 28147-89 is a 64-bit symmetric block cipher with a 256-bit key
developed in the former Soviet Union. Some information on it is avail-
able at <URL:http://vipul.net/gost/>.
This module implements GOST encryption. It supports the Crypt::CBC
interface, with the functions described below. It also provides an
interface that is backwards-compatible with Crypt::GOST 0.41, but its
use in new code is discouraged.
Functions
blocksize
Returns the size (in bytes) of the block (8, in this case).
keysize
Returns the size (in bytes) of the key (32, in this case).
new($key)
This creates a new Crypt::GOST object with the specified key.
encrypt($data)
Encrypts blocksize() bytes of $data and returns the corresponding
ciphertext.
decrypt($data)
Decrypts blocksize() bytes of $data and returns the corresponding
plaintext.
SEE ALSO
Crypt::CBC, Crypt::Twofish, Crypt::TEA
ACKNOWLEDGEMENTS
