=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>!

 # $name ....... one of 'AES', 'Anubis', 'Blowfish', 'CAST5', 'Camellia', 'DES', 'DES_EDE',
 #               'KASUMI', 'Khazad', 'MULTI2', 'Noekeon', 'RC2', 'RC5', 'RC6',

 #               '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
