DSA_size, DSA_bits, DSA_security_bits - get DSA signature size, key bits or security bits
#include <openssl/dsa.h>
int DSA_size(const DSA *dsa);
int DSA_bits(const DSA *dsa);
int DSA_security_bits(const DSA *dsa);
DSA_size() returns the maximum size of an ASN.1 encoded DSA signature for key dsa in bytes. It can be used to determine how much memory must be allocated for a DSA signature.
dsa->q must not be NULL.
DSA_bits() returns the number of bits in key dsa: this is the number of bits in the p parameter.
DSA_security_bits() returns the number of security bits of the given dsa key. See BN_security_bits(3).
DSA_size() returns the signature size in bytes.
DSA_bits() returns the number of bits in the key.
