NAME
SSL_load_client_CA_file, SSL_add_file_cert_subjects_to_stack, SSL_add_dir_cert_subjects_to_stack, SSL_add_store_cert_subjects_to_stack - load certificate names
SYNOPSIS
#include <openssl/ssl.h>
STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
int SSL_add_file_cert_subjects_to_stack(STACK_OF(X509_NAME) *stack,
const char *file)
int SSL_add_dir_cert_subjects_to_stack(STACK_OF(X509_NAME) *stack,
const char *dir)
int SSL_add_store_cert_subjects_to_stack(STACK_OF(X509_NAME) *stack,
const char *store)
DESCRIPTION
SSL_load_client_CA_file() reads certificates from file and returns a STACK_OF(X509_NAME) with the subject names found.
SSL_add_file_cert_subjects_to_stack() reads certificates from file, and adds their subject name to the already existing stack.
SSL_add_dir_cert_subjects_to_stack() reads certificates from every file in the directory dir, and adds their subject name to the already existing stack.
SSL_add_store_cert_subjects_to_stack() loads certificates from the store URI, and adds their subject name to the already existing stack.
NOTES
SSL_load_client_CA_file() reads a file of PEM formatted certificates and extracts the X509_NAMES of the certificates found. While the name suggests the specific usage as support function for RETURN VALUES
The following return values can occur: The operation failed, check out the error stack for the reason. Pointer to the subject names of the successfully read certificates. Load names of CAs from file and use it as a client CA list: ossl_store(7), HISTORY
