This Product includes crypto++ 5.5.2 software under below license
License
The License of Crypto++ is somewhat unusual amongst open source projects. A distinction is made between the library as a com-
pilation (i.e., collection), which is copyrighted by Wei Dai, and the individual files in it, which are public domain (with the excep-
tion of mars.cpp which is subject to its own license, included in that file).
The library is copyrighted as a compilation in order to place certain disclaimers (regarding warranty, export, and patents) in the
license and to keep the attributions and public domain declarations intact when Crypto++ is distributed in source code form. The
fact that individual files are public domain means that legally you can place code segments, entire files, or small sets of files (up
to the limit set by fair use) into your own project and do anything you want with them without worrying about the copyright.
Because one purpose of the project is to act as a repository of public domain (not copyrighted) cryptographic source code, the
code in Crypto++ was either written specifically for this project by its contributors and placed in the public domain, or derived
from other sources that are public domain (again with the exception of mars.cpp).
Compilation Copyright (c) 1995-2009 by Wei Dai. All rights reserved.
This copyright applies only to this software distribution package
as a compilation, and does not imply a copyright on any particular
file in the package.
The following files are copyrighted by their respective original authors,
and their use is subject to additional licenses included in these files.
