X509_REQ_GET_EXTENSIONS(3)

NAME
X509_REQ_get_extensions, X509_REQ_add_extensions, X509_REQ_add_extensions_nid - handle X.509 extension attributes of a CSR

SYNOPSIS
 #include <openssl/x509.h>

 STACK_OF(X509_EXTENSION) *X509_REQ_get_extensions(const X509_REQ *req);
 int X509_REQ_add_extensions(X509_REQ *req, const STACK_OF(X509_EXTENSION) *exts);
 int X509_REQ_add_extensions_nid(X509_REQ *req,
                                 const STACK_OF(X509_EXTENSION) *exts, int nid);

DESCRIPTION
X509_REQ_get_extensions() returns the first list of X.509 extensions found in the attributes of req. The returned list is empty if there are no such extensions in req. The caller is responsible for freeing the list obtained.

X509_REQ_add_extensions_nid() adds to req a list of X.509 extensions exts, using nid to identify the extensions attribute. req is unchanged if exts is NULL or an empty list. This function may be called more than once on the same req and nid. In such case any previous extensions are augmented, where an extension to be added that has the same OID as a pre-existing one replaces this earlier one.

X509_REQ_add_extensions() is like X509_REQ_add_extensions_nid() except that the default NID_ext_req is used.

RETURN VALUES
X509_REQ_get_extensions() returns a pointer to STACK_OF(X509_EXTENSION) or NULL on error.

X509_REQ_add_extensions() and X509_REQ_add_extensions_nid() return 1 on success, 0 on error.
