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