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.

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_handling(); 
...
