SSL_load_client_CA_file(3ssl)
NAME
SSL_load_client_CA_file - load certificate names from file
SYNOPSIS
#include <openssl/ssl.h> STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
DESCRIPTION
SSL_load_client_CA_file() reads certificates from file and returns a
STACK_OF(X509_NAME) with the subject names found.
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.
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_handling();
- ...
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.
