  38 =head1 NOTES
  39
  40 Developers should be aware of the negative performance implications of
  41 calling these functions multiple times and should consider using
  42 L<EVP_CIPHER_fetch(3)> instead.
  43 See L<crypto(7)/Performance> for further information.
  44
  45 =head1 RETURN VALUES
  46
  47 These functions return an B<EVP_CIPHER> structure that contains the
  48 implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
  49 details of the B<EVP_CIPHER> structure.
