<a id="user-content-description-of-problem" class="anchor" href="#description-of-problem" aria-hidden="true"></a>Description of problem:</h2>
<p dir="auto">The documentation for gnutls_x509_crt_export2 claims that</p>
<p dir="auto">"In case of failure a negative error code will be returned, and 0 on success."</p>
<p dir="auto">This is incorrect, as the value of _gnutls_fbase64_encode is sometimes directly returned, which is the length of the exported certificate. Specifically, 0 or greater is returned on success.</p>

<a id="user-content-version-of-gnutls-used" class="anchor" href="#version-of-gnutls-used" aria-hidden="true"></a>Version of gnutls used:</h2>
