<p>DH_new_by_nid() creates and returns a DH structure containing named parameters <b>nid</b>. Currently <b>nid</b> must be <b>NID_ffdhe2048</b>, <b>NID_ffdhe3072</b>, <b>NID_ffdhe4096</b>, <b>NID_ffdhe6144</b>, <b>NID_ffdhe8192</b>, <b>NID_modp_1536</b>, <b>NID_modp_2048</b>, <b>NID_modp_3072</b>, <b>NID_modp_4096</b>, <b>NID_modp_6144</b> or <b>NID_modp_8192</b>.</p>
|
|
|
|
<p>DH_get_nid() determines if the parameters contained in <b>dh</b> match any named safe prime group. It returns the NID corresponding to the matching parameters or <b>NID_undef</b> if there is no match. This function is deprecated.</p>

<p>DH_new_by_nid() returns a set of DH parameters or <b>NULL</b> if an error occurred.</p>
|
|
|
|
<p>DH_get_nid() returns the NID of the matching set of parameters for p and g and optionally q, otherwise it returns <b>NID_undef</b> if there is no match.</p>
