|
|
|
||
|
|
<p>SSL_load_client_CA_file_ex() reads certificates from <i>file</i> and returns a STACK_OF(X509_NAME) with the subject names found. The library context <i>libctx</i> and property query <i>propq</i> are used when fetching algorithms from providers.</p>
|
||
|
|
|
||
|
|
<p>SSL_load_client_CA_file() is similar to SSL_load_client_CA_file_ex() but uses NULL for the library context <i>libctx</i> and property query <i>propq</i>.</p>
|
||
|
|
|
||
|
|
<p>SSL_add_file_cert_subjects_to_stack() reads certificates from <i>file</i>, and adds their subject name to the already existing <i>stack</i>.</p>
|
||
|
|
|
||
|
|
<p>SSL_add_dir_cert_subjects_to_stack() reads certificates from every file in the directory <i>dir</i>, and adds their subject name to the already existing <i>stack</i>.</p>
|
||
|
|
|
||
|
|
<p>SSL_add_store_cert_subjects_to_stack() loads certificates from the <i>store</i> URI, and adds their subject name to the already existing <i>stack</i>.</p>

<p>SSL_load_client_CA_file() 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 <a href="../man3/SSL_CTX_set_client_CA_list.html">SSL_CTX_set_client_CA_list(3)</a>, it is not limited to CA certificates.</p>
