<p>All the OpenSSL EVP_MD implementations understand the following <a href="../man3/OSSL_PARAM.html">OSSL_PARAM(3)</a> entries that are gettable with <a href="../man3/EVP_MD_get_params.html">EVP_MD_get_params(3)</a>, as well as these:</p>

<dt id="blocksize-OSSL_DIGEST_PARAM_BLOCK_SIZE-unsigned-integer">"blocksize" (<b>OSSL_DIGEST_PARAM_BLOCK_SIZE</b>) <unsigned integer></dt>
|
||
|

<dd>
|
||
|
|
|

|
|
<p>The digest block size. The length of the "blocksize" parameter should not exceed that of a <b>size_t</b>.</p>
|
||
|
|
|

|

<p>This value can also be retrieved with <a href="../man3/EVP_MD_get_block_size.html">EVP_MD_get_block_size(3)</a>.</p>

<p>The digest output size. The length of the "size" parameter should not exceed that of a <b>size_t</b>.</p>

<p>Diverse flags that describe exceptional behaviour for the digest. These flags are described in <a href="../man3/EVP_MD_meth_set_flags.html">"DESCRIPTION" in EVP_MD_meth_set_flags(3)</a>.</p>
