<p>SSL_get1_builtin_sigalgs - get list of built-in signature algorithms</p>

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

<pre><code>#include &lt;openssl/tls1.h&gt;

char *SSL_get1_builtin_sigalgs(OSSL_LIB_CTX *libctx);</code></pre>

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

<p>Return the colon-separated list of built-in and available TLS signature algorithms. The string returned must be freed by the user using <a href="../man3/OPENSSL_free.html">OPENSSL_free(3)</a>.</p>

<h1 id="NOTES">NOTES</h1>

<p>The string may be empty (strlen==0) if none of the built-in TLS signature algorithms can be activated, e.g., if suitable providers are missing.</p>

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

<p>NULL may be returned if no memory could be allocated. Otherwise, a newly allocated string is always returned but it may have strlen == 0.</p>
