  40 =head1 NOTES
  41
  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)> instead.
  45 See L<crypto(7)/Performance> for further information.
  46
  47 =head1 RETURN VALUES
  48
  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.
