=head1 NAME

EVP_seed_cbc,
EVP_seed_cfb,
EVP_seed_ecb,
EVP_seed_ofb
- EVP SEED cipher

=head1 SYNOPSIS

 #include <openssl/evp.h>

 const EVP_CIPHER *EVP_seed_cbc(void)
 const EVP_CIPHER *EVP_seed_cfb(void)
 const EVP_CIPHER *EVP_seed_ecb(void)
 const EVP_CIPHER *EVP_seed_ofb(void)

=head1 DESCRIPTION

The SEED encryption algorithm for EVP.

All modes below use a key length of 128 bits and acts on blocks of 128-bits.

=over 4

=item EVP_seed_cbc(),
EVP_seed_cfb(),
EVP_seed_ecb(),
EVP_seed_ofb()

The SEED encryption algorithm in CBC, CFB, ECB and OFB modes respectively.

=head1 RETURN VALUES

These functions return an B<EVP_CIPHER> structure that contains the
implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
details of the B<EVP_CIPHER> structure.
