BoringSSL is a fork of OpenSSL. As such, large parts of it fall under OpenSSL
|
|
|
|
|
licensing. Files that are completely new have a Google copyright and an ISC
|
|
|
|
|
license. This license is reproduced at the bottom of this file.
|
|
|
|
|
|
|
|
|

Contributors to BoringSSL are required to follow the CLA rules for Chromium:

Files in third_party/ have their own licenses, as described therein. The MIT
|
|
|
|
|
license, for third_party/fiat, which, unlike other third_party directories, is
|
|
|
|
|
compiled into non-test libraries, is included below.

The OpenSSL toolkit stays under a dual license, i.e. both the conditions of the
|
|
|
|
|
OpenSSL License and the original SSLeay license apply to the toolkit. See below
|
|
|
|
|
for the actual license texts. Actually both licenses are BSD-style Open Source
|
|
|
|
|
licenses. In case of any license issues related to OpenSSL please contact
