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(3), 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).
BN_get_rfc2409_prime_768(), BN_get_rfc2409_prime_1024(),
BN_get_rfc3526_prime_1536(), BN_get_rfc3526_prime_2048(),
BN_get_rfc3526_prime_3072(), BN_get_rfc3526_prime_4096(),
BN_get_rfc3526_prime_6144(), and BN_get_rfc3526_prime_8192() functions
return a BIGNUM for the specified size from IETF RFC 2409. If bn is
not NULL, the BIGNUM will be set into that location as well.
RETURN VALUES
Defined above.
HISTORY
The functions DH_get_1024_160(3), DH_get_2048_224() and
DH_get_2048_256() were deprecated in OpenSSL 3.0.
