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