     78 =head1 NOTES
     79 
     80 Developers should be aware of the negative performance implications of
     81 calling these functions multiple times and should consider using
     82 L<EVP_CIPHER_fetch(3)> with L<EVP_CIPHER-CAMELLIA(7)> instead.
     83 See L<crypto(7)/Performance> for further information.
     84 
     85 =head1 RETURN VALUES
     86 
     87 These functions return an B<EVP_CIPHER> structure that contains the
     88 implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
     89 details of the B<EVP_CIPHER> structure.
