<p>EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info - enumerate public key methods</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/evp.h&gt;

 size_t EVP_PKEY_meth_get_count(void);
 const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
 void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
                              const EVP_PKEY_METHOD *meth);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>EVP_PKEY_meth_count() returns a count of the number of public key methods available: it includes standard methods and any methods added by the application.</p>

<p>EVP_PKEY_meth_get0() returns the public key method <b>idx</b>. The value of <b>idx</b> must be between zero and EVP_PKEY_meth_get_count() - 1.</p>

<p>EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags associated with the public key method <b>*meth</b>.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>EVP_PKEY_meth_count() returns the number of available public key methods.</p>

<p>EVP_PKEY_meth_get0() return a public key method or <b>NULL</b> if <b>idx</b> is out of range.</p>

<p>EVP_PKEY_meth_get0_info() does not return a value.</p>
