NAME

SSL_load_client_CA_file - load certificate names from file

LIBRARY

libcrypto, -lcrypto

SYNOPSIS


 #include 


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

DESCRIPTION

_S_S_L___l_o_a_d___c_l_i_e_n_t___C_A___f_i_l_e_(_) reads certificates from ffiillee and returns a STACK_OF(X509_NAME) with the subject names found.

NOTES

_S_S_L___l_o_a_d___c_l_i_e_n_t___C_A___f_i_l_e_(_) 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 _S_S_L___C_T_X___s_e_t___c_l_i_e_n_t___C_A___l_i_s_t(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.
