| The following functions have been deprecated since OpenSSL 3.0, and can be |
| hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, |
| see L<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); |
| |
| =head1 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 L<EVP_PKEY_CTX_ctrl(3)> or |
| by setting the B<OSSL_PKEY_PARAM_GROUP_NAME> as specified in |
| L<EVP_PKEY-DH(7)/DH parameters>) 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 B<bn> |
| is not NULL, the BIGNUM will be set into that location as well. |
| |
| =head1 RETURN VALUES |
| |
| Defined above. |
| |
| =head1 HISTORY |
| |
| The functions DH_get_1024_160(), DH_get_2048_224() and DH_get_2048_256() were |
| deprecated in OpenSSL 3.0. |
