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.
