133 SSL_load_client_CA_file \- load certificate names from file
135 .IX Header "SYNOPSIS"
137 \& #include <openssl/ssl.h>
139 \& STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
142 .IX Header "DESCRIPTION"
143 \&\fISSL_load_client_CA_file()\fR reads certificates from \fBfile\fR and returns
144 a \s-1STACK_OF\s0(X509_NAME) with the subject names found.
147 \&\fISSL_load_client_CA_file()\fR reads a file of \s-1PEM\s0 formatted certificates and
148 extracts the X509_NAMES of the certificates found. While the name suggests
149 the specific usage as support function for
150 \&\fISSL_CTX_set_client_CA_list\fR\|(3),
151 it is not limited to \s-1CA\s0 certificates.
153 .IX Header "EXAMPLES"
154 Load names of CAs from file and use it as a client \s-1CA\s0 list:
158 \& STACK_OF(X509_NAME) *cert_names;
161 \& cert_names = SSL_load_client_CA_file("/path/to/CAfile.pem");
162 \& if (cert_names != NULL)
163 \& SSL_CTX_set_client_CA_list(ctx, cert_names);
169 .IX Header "RETURN VALUES"
170 The following return values can occur:
173 The operation failed, check out the error stack for the reason.
174 .IP "Pointer to \s-1STACK_OF\s0(X509_NAME)" 4
175 .IX Item "Pointer to STACK_OF(X509_NAME)"
