 int DSA_generate_key(DSA *a);

=head1 DESCRIPTION

a new key pair and stores it in B<a-E<gt>pub_key> and B<a-E<gt>priv_key>.

The PRNG must be seeded prior to calling DSA_generate_key().

=head1 RETURN VALUE

DSA_generate_key() returns 1 on success, 0 otherwise.
The error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.

=head1 SEE ALSO

L<dsa(3)|dsa(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, L<rand(3)|rand(3)>,
L<DSA_generate_parameters(3)|DSA_generate_parameters(3)>

=head1 HISTORY

DSA_generate_key() is available since SSLeay 0.8.
