<p>X509V3_set_ctx, X509V3_set_issuer_pkey - X.509 v3 extension generation utilities</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include <openssl/x509v3.h>
void X509V3_set_ctx(X509V3_CTX *ctx, X509 *issuer, X509 *subject,
X509_REQ *req, X509_CRL *crl, int flags);
int X509V3_set_issuer_pkey(X509V3_CTX *ctx, EVP_PKEY *pkey);</code></pre>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>X509V3_set_ctx() fills in the basic fields of <i>ctx</i> of type <b>X509V3_CTX</b>, providing details potentially needed by functions producing X509 v3 extensions, e.g., to look up values for filling in authority key identifiers. Any of <i>subject</i>, <i>req</i>, or <i>crl</i> may be provided, pointing to a certificate, certification request, or certificate revocation list, respectively. When constructing the subject key identifier of a certificate by computing a hash value of its public key, the public key is taken from <i>subject</i> or <i>req</i>. Similarly, when constructing subject alternative names from any email addresses contained in a subject DN, the subject DN is taken from <i>subject</i> or <i>req</i>. If <i>subject</i> or <i>crl</i> is provided, <i>issuer</i> should point to its issuer, for instance to help generating an authority key identifier extension. Note that if <i>subject</i> is provided, <i>issuer</i> may be the same as <i>subject</i>, which means that <i>subject</i> is self-issued (or even self-signed). <i>flags</i> may be 0 or contain <b>X509V3_CTX_TEST</b>, which means that just the syntax of extension definitions is to be checked without actually producing an extension, or <b>X509V3_CTX_REPLACE</b>, which means that each X.509v3 extension added as defined in some configuration section shall replace any already existing extension with the same OID.</p>
<p>X509V3_set_issuer_pkey() explicitly sets the issuer private key of the certificate that has been provided in <i>ctx</i>. This should be done for self-issued certificates (which may be self-signed or not) to provide fallback data for the authority key identifier extension.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>X509V3_set_ctx() and X509V3_set_issuer_pkey() return 1 on success and 0 on error.</p>

<h1 id="HISTORY">HISTORY</h1>
<p>X509V3_set_issuer_pkey() was added in OpenSSL 3.0.</p>
<p>CTX_TEST was deprecated in OpenSSL 3.0; use X509V3_CTX_TEST instead.</p>
