NAME¶
DH_size, DH_bits - get Diffie-Hellman prime sizeSYNOPSIS¶
#include <openssl/dh.h>int DH_size(const DH *dh);
int DH_bits(const DH *dh);
DESCRIPTION¶
DH_size() returns the Diffie-Hellman prime size in bytes. It can be used to determine how much memory must be allocated for the shared secret computed by DH_compute_key().DH_bits() returns the number of significant bits.
dh and dh->p must not be NULL.
RETURN VALUE¶
The size.SEE ALSO¶
