1=pod 2 3=head1 NAME 4 5X509_REQ_get_extensions, 6X509_REQ_add_extensions, X509_REQ_add_extensions_nid 7- handle X.509 extension attributes of a CSR 8 9=head1 SYNOPSIS 10 11 #include <openssl/x509.h> 12 13 STACK_OF(X509_EXTENSION) *X509_REQ_get_extensions(X509_REQ *req); 14 int X509_REQ_add_extensions(X509_REQ *req, const STACK_OF(X509_EXTENSION) *exts); 15 int X509_REQ_add_extensions_nid(X509_REQ *req, 16 const STACK_OF(X509_EXTENSION) *exts, int nid); 17 18=head1 DESCRIPTION 19 20X509_REQ_get_extensions() returns the first list of X.509 extensions 21found in the attributes of I<req>. 22The returned list is empty if there are no such extensions in I<req>. 23The caller is responsible for freeing the list obtained. 24 25X509_REQ_add_extensions() adds to I<req> a list of X.509 extensions I<exts>, 26which must not be NULL, using the default B<NID_ext_req>. 27This function must not be called more than once on the same I<req>. 28 29X509_REQ_add_extensions_nid() is like X509_REQ_add_extensions() 30except that I<nid> is used to identify the extensions attribute. 31This function must not be called more than once with the same I<req> and I<nid>. 32 33=head1 RETURN VALUES 34 35X509_REQ_get_extensions() returns a pointer to B<STACK_OF(X509_EXTENSION)> 36or NULL on error. 37 38X509_REQ_add_extensions() and X509_REQ_add_extensions_nid() 39return 1 on success, 0 on error. 40 41=head1 COPYRIGHT 42 43Copyright 2022-2024 The OpenSSL Project Authors.
