<p>The X.509 module provides X.509 support which includes: </p>
<ul>
<li>X.509 certificate (CRT) reading (see <code><a class="el" href="compat-1_82_8h.html#a70b3229deb69f767e7ae0231075690b7">x509parse_crt()</a></code> and <code><a class="el" href="compat-1_82_8h.html#a48601801c56e34c247c52b3ca39e8bcb">x509parse_crtfile()</a></code>).</li>
<li>X.509 certificate revocation list (CRL) reading (see <code><a class="el" href="compat-1_82_8h.html#a7da761c33c4c4f99afde1d0f62a6e6fb">x509parse_crl()</a></code> and<code><a class="el" href="compat-1_82_8h.html#ac4ba592ae83c5979c2f2628b6c4b1f47">x509parse_crlfile()</a></code>).</li>
<li>X.509 (RSA and ECC) private key reading (see <code><a class="el" href="compat-1_82_8h.html#a4b24fc4d228c28e98ff8e2cd4ca97a77">x509parse_key()</a></code> and <code><a class="el" href="compat-1_82_8h.html#a5c8d14f73b6167dddb70076af7d511c3">x509parse_keyfile()</a></code>).</li>
<li>X.509 certificate signature verification (see <code><a class="el" href="compat-1_82_8h.html#a09c96bf79195df763c48a3cfd0212f2b">x509parse_verify()</a></code>)</li>
<li>X.509 certificate writing and certificate request writing (see <code><a class="el" href="x509__crt_8h.html#a7300897079a27c5fa424c9653081b286" title="Write a built up certificate to a X509 DER structure Note: data is written at the end of the buffer! ...">x509write_crt_der()</a></code> and <code><a class="el" href="x509__csr_8h.html#abd7a30a6b00b0b34ffa6792593eab737" title="Write a CSR (Certificate Signing Request) to a DER structure Note: data is written at the end of the ...">x509write_csr_der()</a></code>).</li>
</ul>
<p>This module can be used to build a certificate authority (CA) chain and verify its signature. It is also used to generate Certificate Signing Requests and X509 certificates just as a CA would do. </p>

that specific certificate and the certificate depth from
the bottom (Peer cert depth = 0).
