24 The SEED encryption algorithm for EVP.
26 All modes below use a key length of 128 bits and acts on blocks of 128-bits.
36 The SEED encryption algorithm in CBC, CFB, ECB and OFB modes respectively.
42 Developers should be aware of the negative performance implications of
43 calling these functions multiple times and should consider using
44 L<EVP_CIPHER_fetch(3)> with L<EVP_CIPHER-SEED(7)> instead.
45 See L<crypto(7)/Performance> for further information.
49 These functions return an B<EVP_CIPHER> structure that contains the
50 implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
51 details of the B<EVP_CIPHER> structure.
