X509V3_SET_CTX(3ossl) OpenSSL X509V3_SET_CTX(3ossl)
NAME
X509V3_set_ctx, X509V3_set_issuer_pkey - X.509 v3 extension generation
utilities
SYNOPSIS
#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);
DESCRIPTION
X509V3_set_ctx(3) fills in the basic fields of ctx of type X509V3_CTX,
providing details potentially needed by functions producing X509 v3
extensions. These may make use of fields of the certificate subject,
the certification request req, or the certificate revocation list crl.
At most one of these three parameters can be non-NULL. When
constructing the subject key identifier of a certificate by computing a
hash value of its public key, the public key is taken from subject or
req. Similarly, when constructing subject alternative names from any
email addresses contained in a subject DN, the subject DN is taken from
subject or req. If subject or crl is provided, issuer should point to
its issuer, for instance as a reference for generating the authority
key identifier extension. issuer may be the same pointer value as
subject (which usually is an indication that the subject certificate is
self-issued or even self-signed). In this case the fallback source for
generating the authority key identifier extension will be taken from
any value provided using X509V3_set_issuer_pkey(). flags may be 0 or
contain X509V3_CTX_TEST, which means that just the syntax of extension
definitions is to be checked without actually producing any extension,
or X509V3_CTX_REPLACE, which means that each X.509v3 extension added as
defined in some configuration section shall replace any already
existing extension with the same OID.
X509V3_set_issuer_pkey() explicitly sets the issuer private key of the
subject certificate that has been provided in ctx. This should be done
in case the issuer and subject arguments to X509V3_set_ctx(3) have the
same pointer value to provide fallback data for the authority key
identifier extension.
RETURN VALUES
X509V3_set_ctx(3) and X509V3_set_issuer_pkey() return 1 on success and 0
on error.
