<p>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 <a href="../man3/EVP_PKEY_CTX_ctrl.html">EVP_PKEY_CTX_ctrl(3)</a> or by setting the <b>OSSL_PKEY_PARAM_GROUP_NAME</b> as specified in <a href="../man7/EVP_PKEY-DH.html">"DH parameters" in EVP_PKEY-DH(7)</a>) to one of "dh_1024_160", "dh_2048_224" or "dh_2048_256".</p>
