+=head1 NAME
+
+Crypt::Cipher::SEED - Symmetric cipher SEED, key size: 128 bits
+
+=head1 SYNOPSIS
+
+  ### example 1
+  use Crypt::Mode::CBC;
+
+  my $key = '...'; # length has to be valid key size for this cipher
+  my $iv = '...';  # 16 bytes
+  my $cbc = Crypt::Mode::CBC->new('SEED');
+  my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
+
+  ### example 2 (slower)
+  use Crypt::CBC;
+  use Crypt::Cipher::SEED;
+
+  my $key = '...'; # length has to be valid key size for this cipher
+  my $iv = '...';  # 16 bytes
+  my $cbc = Crypt::CBC->new( -cipher=>'Cipher::SEED', -key=>$key, -iv=>$iv );
+  my $ciphertext = $cbc->encrypt("secret data");
+
+=head1 DESCRIPTION
+
+This module implements the SEED cipher. Provided interface is compliant with L<Crypt::CBC|Crypt::CBC> module.
+
+B<BEWARE:> This module implements just elementary "one-block-(en|de)cryption" operation - if you want to
+encrypt/decrypt generic data you have to use some of the cipher block modes - check for example
+L<Crypt::Mode::CBC|Crypt::Mode::CBC>, L<Crypt::Mode::CTR|Crypt::Mode::CTR> or L<Crypt::CBC|Crypt::CBC> (which will be slower).
