=head1 NAME
DSA_size, DSA_bits - get DSA signature size or key bits
=head1 SYNOPSIS
#include <openssl/dsa.h>
int DSA_size(const DSA *dsa);
int DSA_bits(const DSA *dsa);
=head1 DESCRIPTION
DSA_size() returns the maximum size of an ASN.1 encoded DSA signature
for key B<dsa> in bytes. It can be used to determine how much memory must
be allocated for a DSA signature.
B<dsa-E<gt>q> must not be B<NULL>.
DSA_bits() returns the number of bits in key B<dsa>: this is the number
of bits in the B<p> parameter.
=head1 RETURN VALUE
DSA_size() returns the size in bytes.
DSA_bits() returns the number of bits in the key.
=head1 SEE ALSO
L<dsa(3)>, L<DSA_sign(3)>
