NAME

SSL_CTX_set_client_CA_list, SSL_set_client_CA_list, SSL_CTX_add_client_CA,
SSL_add_client_CA - set list of CAs sent to the client when requesting a
client certificate
 

SYNOPSIS

 #include <openssl/ssl.h>

 void SSL_CTX_set_client_CA_list(SSL_CTX *ctx, STACK_OF(X509_NAME) *list);
 void SSL_set_client_CA_list(SSL *s, STACK_OF(X509_NAME) *list);
 int SSL_CTX_add_client_CA(SSL_CTX *ctx, X509 *cacert);
 int SSL_add_client_CA(SSL *ssl, X509 *cacert);

DESCRIPTION

SSL_set_client_CA_list() sets the list of CAs sent to the client when requesting a client certificate for the chosen ssl, overriding the setting valid for ssl's SSL_CTX object.

SSL_CTX_add_client_CA() adds the CA name extracted from cacert to the list of CAs sent to the client when requesting a client certificate for ctx.

SSL_add_client_CA() adds the CA name extracted from cacert to the list of CAs sent to the client when requesting a client certificate for the chosen ssl, overriding the setting valid for ssl's SSL_CTX object.  

NOTES

This list must explicitly be set using SSL_CTX_set_client_CA_list() for ctx and SSL_set_client_CA_list() for the specific ssl. The list specified overrides the previous setting. The CAs listed do not become trusted (list only contains the names, not the complete certificates); use SSL_CTX_load_verify_locations(3) to additionally load them for verification.

If the list of acceptable CAs is compiled in a file, the SSL_load_client_CA_file(3) function can be used to help importing the necessary data.

SSL_CTX_add_client_CA() and SSL_add_client_CA() can be used to add additional items the list of client CAs. If no list was specified before using SSL_CTX_set_client_CA_list() or SSL_set_client_CA_list(), a new client CA list for ctx or ssl (as appropriate) is opened.

These functions are only useful for TLS/SSL servers.  

RETURN VALUES

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

1

The operation succeeded.

0

A failure while manipulating the STACK_OF(X509_NAME) object occurred or the X509_NAME could not be extracted from cacert. Check the error stack to find out the reason.
