SSL_load_client_CA_file(3)SSL_load_client_CA_file(3)NAMESSL_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
The SSL_load_client_CA_file() function reads certificates from file and
returns a STACK_OF(X509_NAME) with the subject names found.
NOTES
The SSL_load_client_CA_file() function 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 for the
SSL_CTX_set_client_CA_list() function, it is not limited to CA certifi‐
cates.
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: The operation failed, check out
the error stack for the reason. Pointer to the subject names of the
successfully read certificates.
