NAME

SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs

SYNOPSIS

 #include <openssl/ssl.h>

 STACK_OF(X509_NAME) *SSL_get_client_CA_list(const SSL *s);
 STACK_OF(X509_NAME) *SSL_CTX_get_client_CA_list(const SSL_CTX *ctx);

DESCRIPTION

SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for ctx using SSL_CTX_set_client_CA_list(3).

SSL_get_client_CA_list() returns the list of client CAs explicitly set for ssl using SSL_set_client_CA_list() or ssl's SSL_CTX object with SSL_CTX_set_client_CA_list(3), when in server mode. In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the server, if any.

RETURN VALUES

SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return diagnostic information.

SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return values:

STACK_OF(X509_NAMES): List of CA names explicitly set (for ctx or in server mode) or send by the server (client mode).
NULL: No client CA list was explicitly set (for ctx or in server mode) or the server did not send a list of CAs (client mode).
