A private key will be de- crypted if the optional password argument is specified. tls_unload_file() unloads the memory that was returned from an earlier tls_load_file() call, ensuring that the memory contents is discarded. tls_default_ca_cert_file() returns the path of the file that contains the default root certificates. tls_config_set_ca_file() loads a file containing the root certificates. tls_config_set_ca_path() sets the path (directory) which should be searched for root certificates. tls_config_set_ca_mem() sets the root certificates directly from memory. tls_config_set_cert_file() loads a file containing the public certificate. tls_config_set_cert_mem() sets the public certificate directly from memory. tls_config_set_crl_file() loads a file containing the Certificate Revoca- tion List (CRL). tls_config_set_crl_mem() sets the CRL directly from memory. tls_config_set_key_file() loads a file containing the private key. tls_config_set_key_mem() directly sets the private key from memory. tls_config_set_ocsp_staple_file() loads a file containing a DER-encoded OCSP response to be stapled during the TLS handshake. tls_config_set_ocsp_staple_mem() sets a DER-encoded OCSP response to be stapled during the TLS handshake from memory. tls_config_set_keypair_file() loads two files from which the public cer- tificate and private key will be read. tls_config_set_keypair_mem() directly sets the public certificate and pri- vate key from memory. tls_config_set_keypair_ocsp_file() loads three files containing the public certificate, private key, and DER-encoded OCSP staple. tls_config_set_keypair_ocsp_mem() directly sets the public certificate, private key, and DER-encoded OCSP staple from memory. tls_config_add_keypair_file() adds an additional public certificate and private key from the specified files, used as an alternative certificate for Server Name Indication (server only). tls_config_add_keypair_mem() adds an additional public certificate and pri- vate key from memory, used as an alternative certificate for Server Name Indication (server only). tls_config_add_keypair_ocsp_file() adds an additional public certificate, private key, and DER-encoded OCSP staple from the specified files, used as an alternative certificate for Server Name Indication (server only). tls_config_add_keypair_ocsp_mem() adds an additional public certificate, private key, and DER-encoded OCSP staple from memory, used as an alterna- tive certificate for Server Name Indication (server only). tls_config_clear_keys() clears any secret keys from memory. tls_config_set_verify_depth() limits the number of intermediate certifi- cates that will be followed during certificate validation. tls_config_verify_client() enables client certificate verification, requir- ing the client to send a certificate (server only). tls_config_verify_client_optional() enables client certificate verifica- tion, without requiring the client to send a certificate (server only). RETURN VALUES tls_load_file() returns NULL on error or an out of memory condition. The other functions return 0 on success or -1 on error.
