This directory contains the copy of BoringSSL used by the Widevine CDM. On most platforms, the Widevine CDM statically links against this copy of BoringSSL. To update this directory to the latest version of BoringSSL, run UPDATE_BORINGSSL.sh, which updates BoringSSL to the latest public release. Note that this will replace the entire contents of the kit/ subdirectory.

The kit/ subdirectory contains the BoringSSL source code and several autogenerated files derived from it. The files in this directory are maintained by tools and should not be edited by hand.

This top-level directory contains files written by hand that are not replaced when the UPDATE_BORINGSSL.sh script is run.
