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

<pre><code> #include &lt;openssl/x509.h&gt;

 X509 *d2i_X509_AUX(X509 **px, const unsigned char **in, long len);
 int i2d_X509_AUX(X509 *x, unsigned char **out);
 int i2d_re_X509_tbs(X509 *x, unsigned char **out);
 int i2d_re_X509_CRL_tbs(X509_CRL *crl, unsigned char **pp);

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

<p>The X509 encode and decode routines encode and parse an <b>X509</b> structure, which represents an X509 certificate.</p>

<p>d2i_X509_AUX() is similar to <a href="../man3/d2i_X509.html">d2i_X509(3)</a> but the input is expected to consist of an X509 certificate followed by auxiliary trust information. This is used by the PEM routines to read &quot;TRUSTED CERTIFICATE&quot; objects. This function should not be called on untrusted input.</p>

<p>i2d_X509_AUX() is similar to <a href="../man3/i2d_X509.html">i2d_X509(3)</a>, but the encoded output contains both the certificate and any auxiliary trust information. This is used by the PEM routines to write &quot;TRUSTED CERTIFICATE&quot; objects. Note that this is a non-standard OpenSSL-specific data format.</p>

<p>i2d_re_X509_tbs() is similar to <a href="../man3/i2d_X509.html">i2d_X509(3)</a> except it encodes only the TBSCertificate portion of the certificate. i2d_re_X509_CRL_tbs() and i2d_re_X509_REQ_tbs() are analogous for CRL and certificate request, respectively. The &quot;re&quot; in <b>i2d_re_X509_tbs</b> stands for &quot;re-encode&quot;, and ensures that a fresh encoding is generated in case the object has been modified after creation (see the BUGS section).</p>

<p>The encoding of the TBSCertificate portion of a certificate is cached in the <b>X509</b> structure internally to improve encoding performance and to ensure certificate signatures are verified correctly in some certificates with broken (non-DER) encodings.</p>

<p>If, after modification, the <b>X509</b> object is re-signed with X509_sign(), the encoding is automatically renewed. Otherwise, the encoding of the TBSCertificate portion of the <b>X509</b> can be manually renewed by calling i2d_re_X509_tbs().</p>

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

<p>d2i_X509_AUX() returns a valid <b>X509</b> structure or NULL if an error occurred.</p>

<p>i2d_X509_AUX() returns the length of encoded data or -1 on error.</p>

<p>i2d_re_X509_tbs(), i2d_re_X509_CRL_tbs() and i2d_re_X509_REQ_tbs() return the length of encoded data or 0 on error.</p>
