=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 VALUE
|
|
|
|
DSA_size() returns the signature size in bytes.
|
|
|
|
DSA_bits() returns the number of bits in the key.
