6 X509V3_set_issuer_pkey - X.509 v3 extension generation utilities
10 #include <openssl/x509v3.h>
12 void X509V3_set_ctx(X509V3_CTX *ctx, X509 *issuer, X509 *subject,
13 X509_REQ *req, X509_CRL *crl, int flags);
14 int X509V3_set_issuer_pkey(X509V3_CTX *ctx, EVP_PKEY *pkey);
18 X509V3_set_ctx() fills in the basic fields of I<ctx> of type B<X509V3_CTX>,
19 providing details potentially needed by functions producing X509 v3 extensions,
20 e.g., to look up values for filling in authority key identifiers.
21 Any of I<subj>, I<req>, or I<crl> may be provided, pointing to a certificate,
22 certification request, or certificate revocation list, respectively.
23 If I<subj> or I<crl> is provided, I<issuer> should point to its issuer,
24 for instance to help generating an authority key identifier extension.
25 Note that if I<subj> is provided, I<issuer> may be the same as I<subj>,
26 which means that I<subj> is self-issued (or even self-signed).
28 or contain B<X509V3_CTX_TEST>, which means that just the syntax of
29 extension definitions is to be checked without actually producing an extension,
30 or B<X509V3_CTX_REPLACE>, which means that each X.509v3 extension added as
31 defined in some configuration section shall replace any already existing
32 extension with the same OID.
34 X509V3_set_issuer_pkey() explicitly sets the issuer private key of
35 the certificate that has been provided in I<ctx>.
36 This should be done for self-issued certificates (which may be self-signed
37 or not) to provide fallback data for the authority key identifier extension.
41 X509V3_set_ctx() and X509V3_set_issuer_pkey()
42 return 1 on success and 0 on error.
50 X509V3_set_issuer_pkey() was added in OpenSSL 3.0.
52 CTX_TEST was deprecated in OpenSSL 3.0; use X509V3_CTX_TEST instead.
