NAME¶
DSA_size, DSA_bits - get DSA signature size or key bitsSYNOPSIS¶
#include <openssl/dsa.h> int DSA_size(const DSA *dsa); int DSA_bits(const DSA *dsa);
DESCRIPTION¶
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.
RETURN VALUE¶
DSA_size() returns the size in bytes.DSA_bits() returns the number of bits in the key.
