<p>PKCS12_parse - parse a PKCS#12 structure</p>

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

<pre><code>#include &lt;openssl/pkcs12.h&gt;

int PKCS12_parse(PKCS12 *p12, const char *pass, EVP_PKEY **pkey, X509 **cert,
                 STACK_OF(X509) **ca);</code></pre>

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

<p>PKCS12_parse() parses a PKCS12 structure.</p>

<p><b>p12</b> is the <b>PKCS12</b> structure to parse. <b>pass</b> is the passphrase to use. If successful the private key will be written to <b>*pkey</b>, the corresponding certificate to <b>*cert</b> and any additional certificates to <b>*ca</b>.</p>

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

<p>Each of the parameters <b>pkey</b>, <b>cert</b>, and <b>ca</b> can be NULL in which case the private key, the corresponding certificate, or the additional certificates, respectively, will be discarded. If any of <b>pkey</b> and <b>cert</b> is non-NULL the variable it points to is initialized. If <b>ca</b> is non-NULL and <b>*ca</b> is NULL a new STACK will be allocated. If <b>ca</b> is non-NULL and <b>*ca</b> is a valid STACK then additional certificates are appended in the given order to <b>*ca</b>.</p>

<p>The <b>friendlyName</b> and <b>localKeyID</b> attributes (if present) on each certificate will be stored in the <b>alias</b> and <b>keyid</b> attributes of the <b>X509</b> structure.</p>

<p>The parameter <b>pass</b> is interpreted as a string in the UTF-8 encoding. If it is not valid UTF-8, then it is assumed to be ISO8859-1 instead.</p>

<p>In particular, this means that passwords in the locale character set (or code page on Windows) must potentially be converted to UTF-8 before use. This may include passwords from local text files, or input from the terminal or command line. Refer to the documentation of <a href="../man3/UI_OpenSSL.html">UI_OpenSSL(3)</a>, for example.</p>

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

<p>PKCS12_parse() returns 1 for success and zero if an error occurred.</p>

<p>The error can be obtained from <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a></p>

<h1 id="BUGS">BUGS</h1>

<p>Only a single private key and corresponding certificate is returned by this function. More complex PKCS#12 files with multiple private keys will only return the first match.</p>

<p>Only <b>friendlyName</b> and <b>localKeyID</b> attributes are currently stored in certificates. Other attributes are discarded.</p>

<p>Attributes currently cannot be stored in the private key <b>EVP_PKEY</b> structure.</p>
