SYNOPSIS #include <openssl/dh.h>
const BIGNUM *BN_get0_nist_prime_192(void); const BIGNUM *BN_get0_nist_prime_224(void); const BIGNUM *BN_get0_nist_prime_256(void); const BIGNUM *BN_get0_nist_prime_384(void); const BIGNUM *BN_get0_nist_prime_521(void);
BIGNUM *BN_get_rfc2409_prime_768(BIGNUM *bn); BIGNUM *BN_get_rfc2409_prime_1024(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_1536(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_2048(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_3072(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_4096(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_6144(BIGNUM *bn); BIGNUM *BN_get_rfc3526_prime_8192(BIGNUM *bn);
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):
#include <openssl/dh.h>
DH *DH_get_1024_160(void); DH *DH_get_2048_224(void); DH *DH_get_2048_256(void);
DESCRIPTION DH_get_1024_160(), DH_get_2048_224(), and DH_get_2048_256() each return a DH object for the IETF RFC 5114 value. These functions are deprecated. Applications should instead use EVP_PKEY_CTX_set_dh_rfc5114() and EVP_PKEY_CTX_set_dhx_rfc5114() as described in EVP_PKEY_CTX_ctrl(3) or by setting the OSSL_PKEY_PARAM_GROUP_NAME as specified in "DH parameters" in EVP_PKEY-DH(7)) to one of "dh_1024_160", "dh_2048_224" or "dh_2048_256".
BN_get0_nist_prime_192(), BN_get0_nist_prime_224(), BN_get0_nist_prime_256(), BN_get0_nist_prime_384(), and BN_get0_nist_prime_521() functions return a BIGNUM for the specific NIST prime curve (e.g., P-256).

HISTORY The functions DH_get_1024_160(), DH_get_2048_224() and DH_get_2048_256() were deprecated in OpenSSL 3.0.
