|
|
<p>Support for computing KMAC MACs through the <strong>EVP_MAC</strong> API.</p>
|

<p>
|
|
</p>
|
|
<h2><a name="identity">Identity</a></h2>
|
|
<p>These implementations are identified with one of these names and
|
|
properties, to be used with EVP_MAC_fetch():</p>

<h2><a name="supported_parameters">Supported parameters</a></h2>
|
|
<p>The general description of these parameters can be found in
|
|
<em>EVP_MAC(3)/PARAMETERS</em>.</p>
|
|
<p>All these parameters can be set with <code>EVP_MAC_CTX_set_params()</code>.
|
|
Furthermore, the "size" parameter can be retrieved with
|
|
<code>EVP_MAC_CTX_get_params()</code>, or with <code>EVP_MAC_size()</code>.
|
|
The length of the "size" parameter should not exceed that of a <strong>size_t</strong>.</p>
|
|
<dl>

<dt><strong><a name="key_ossl_mac_param_key_octet_string" class="item">"key" (<strong>OSSL_MAC_PARAM_KEY</strong>) <octet string></a></strong></dt>

|
|
|
|
</dl>
|
|
<p>The "xof" parameter value is expected to be 1 or 0. Use 1 to enable XOF
|
|
mode. If XOF is enabled then the output length that is encoded as part of
|
|
the input stream is set to zero.</p>
