 * To enable logs in BoringSSL:
 *  - define ENABLE_SSL_LOG macros at compile time, e.g. uncomment corresponding
 *    line in boringssl_defaults section of Android.bp.sec.bldpp file
 *  - include <openssl/log.h>
 *
 * To enable logs outside BoringSSL:
 *  - define ENABLE_SSL_LOG macros at compile time to enable logs
 *  - for Android builds define ANDROID_LOG macros at compile time to use
 *    Android logging subsystem
 *  - include <openssl/log.h>
 *
 * Example:
 *
 * #include <openssl/log.h>
 * ...
 * LOGE("this is an example of ERROR message");
 * LOGW("this is an example of WARNING message");
 * LOGI("this is an example of INFORMATIONAL message");
 * LOGD("this is an example of DEBUG message");
 * ...
