+ ca_path (str)

+ Sets the path with the trusted CA files, to be given as parameter
+ SSL_CTX_load_verify_locations(). The certificates in ca_path are only
+ looked up when required, e.g. when building the certificate chain
+ or when actually performing the verification of a peer certificate. They
+ are not given to the client (not loaded to be provided to
+ SSL_CTX_set_client_CA_list()), only the ones in ca_list files are sent
+ to the client. It requires to use c_rehash to generate the hash map
+ for certificate search, for more see the manual of libssl for
+ SSL_CTX_load_verify_locations() function.
