+=head1 NOTES
+
+Developers should be aware of the negative performance implications of
+calling these functions multiple times and should consider using
+L<EVP_MD_fetch(3)> with L<EVP_MD-SHA2(7)>instead.
+See L<crypto(7)/Performance> for further information.
 
 =head1 RETURN VALUES
 
 These functions return a B<EVP_MD> structure that contains the
-implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
+implementation of the message digest. See L<EVP_MD_meth_new(3)> for
 details of the B<EVP_MD> structure.
