 # 8.1 Debugging and Logging
 
 wolfSSL (formerly CyaSSL) has support for debugging through log messages in environments where debugging is limited. To turn logging on use the function _wolfSSL\_Debugging\_ON()_ and to turn it off use _wolfSSL\_Debugging\_OFF()_. In a normal build (release mode) these functions will have no effect. In a debug build, define **DEBUG\_WOLFSSL** to ensure these functions are turned on.
