SSL_LOAD_CLIENT_CA_FILE(3) | OpenSSL | SSL_LOAD_CLIENT_CA_FILE(3) |
NAME¶
SSL_load_client_CA_file, SSL_add_file_cert_subjects_to_stack, SSL_add_dir_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)
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.
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 SSL_CTX_set_client_CA_list(3), it is not limited to CA certificates.
RETURN VALUES¶
The following return values can occur:
- NULL
- The operation failed, check out the error stack for the reason.
- Pointer to STACK_OF(X509_NAME)
- Pointer to the subject names of the successfully read certificates.
EXAMPLES¶
Load names of CAs from file and use it as a client CA list:
SSL_CTX *ctx; STACK_OF(X509_NAME) *cert_names; ... cert_names = SSL_load_client_CA_file("/path/to/CAfile.pem"); if (cert_names != NULL) SSL_CTX_set_client_CA_list(ctx, cert_names); else /* error */ ...
