#include <openssl/dh.h>
The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):
int DH_bits(const DH *dh); int DH_size(const DH *dh); int DH_security_bits(const DH *dh);
DH_bits() returns the number of significant bits.
dh and dh->p must not be NULL.
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(3).
DH_security_bits() returns the number of security bits of the given dh key. See BN_security_bits(3).
DH_size() returns the prime size of Diffie-Hellman in bytes, or -1 if dh doesn't hold any key parameters.
DH_security_bits() returns the number of security bits, or -1 if dh doesn't hold any key parameters.
