=head1 NAME
DSA_size, DSA_bits, DSA_security_bits - get DSA signature size, key bits or security bits
=head1 SYNOPSIS
#include <openssl/dsa.h>
int DSA_size(const DSA *dsa);
int DSA_bits(const DSA *dsa);
int DSA_security_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.
DSA_security_bits() returns the number of security bits of the given B<dsa>
key. See L<BN_security_bits(3)>.
=head1 RETURN VALUES
DSA_size() returns the signature size in bytes.
DSA_bits() returns the number of bits in the key.
