Synopsis

#include <openssl/ssl.h>

STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);

Detailed 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(), 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.
