=head1 NAME
Crypt::Mode::ECB - Block cipher mode ECB [Electronic codebook]
=head1 SYNOPSIS
use Crypt::Mode::ECB;
my $m = Crypt::Mode::ECB->new('AES');
#(en|de)crypt at once
my $ciphertext = $m->encrypt($plaintext, $key);
my $plaintext = $m->decrypt($ciphertext, $key);
#encrypt more chunks
$m->start_encrypt($key);
my $ciphertext = $m->add('some data');
$ciphertext .= $m->add('more data');
$ciphertext .= $m->finish;
#decrypt more chunks
$m->start_decrypt($key);
my $plaintext = $m->add($some_ciphertext);
$plaintext .= $m->add($more_ciphertext);
$plaintext .= $m->finish;
=head1 DESCRIPTION
This module implements ECB cipher mode. B<NOTE:> it works only with ciphers from L<CryptX> (Crypt::Cipher::NNNN).
B<BEWARE: ECB is inherently insecure>, if you are not sure go for L<Crypt::Mode::CBC>!
=head1 METHODS
=head2 new
my $m = Crypt::Mode::ECB->new($name);
#or
my $m = Crypt::Mode::ECB->new($name, $padding);
#or
my $m = Crypt::Mode::ECB->new($name, $padding, $cipher_rounds);
# $name ....... one of 'AES', 'Anubis', 'Blowfish', 'CAST5', 'Camellia', 'DES', 'DES_EDE',
# 'KASUMI', 'Khazad', 'MULTI2', 'Noekeon', 'RC2', 'RC5', 'RC6',
# 'SAFERP', 'SAFER_K128', 'SAFER_K64', 'SAFER_SK128', 'SAFER_SK64',
# 'SEED', 'Skipjack', 'Twofish', 'XTEA', 'IDEA', 'Serpent'
# simply any <NAME> for which there exists Crypt::Cipher::<NAME>
# $padding .... 0 no padding (plaintext size has to be multiple of block length)
# 1 PKCS5 padding, Crypt::CBC's "standard" - DEFAULT
# 2 Crypt::CBC's "oneandzeroes"
# 3 ANSI X.923 padding
# 4 zero padding
# 5 zero padding (+a block of zeros if the output length is divisible by the blocksize)
# $cipher_rounds ... optional num of rounds for given cipher
