-RSA_generate_key() is deprecated (new applications should use
-RSA_generate_key_ex() instead). RSA_generate_key() works in the same way as
-RSA_generate_key_ex() except it uses "old style" call backs. See

=head1 RETURN VALUE
RSA_generate_key_ex() returns 1 on success or 0 on error.
-RSA_generate_key() returns the key on success or B<NULL> on error.

The error codes can be obtained by L<ERR_get_error(3)>.

B<BN_GENCB_call(cb, 2, x)> is used with two different meanings.
-RSA_generate_key() goes into an infinite loop for illegal input values.
