| =head1 NAME |
| |
| SSL_load_client_CA_file - load certificate names from file |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/ssl.h> |
| |
| STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file); |
| |
| =head1 DESCRIPTION |
| |
| SSL_load_client_CA_file() reads certificates from B<file> and returns |
| a STACK_OF(X509_NAME) with the subject names found. |
| |
| =head1 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 |
| L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>, |
| it is not limited to CA certificates. |
| |
| =head1 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(); |
| ... |
| |
| =head1 RETURN VALUES |
| |
| The following return values can occur: |
| |
| =over 4 |
| |
| =item NULL |
| |
| The operation failed, check out the error stack for the reason. |
| |
| =item Pointer to STACK_OF(X509_NAME) |
| |
| Pointer to the subject names of the successfully read certificates. |
