Bitcoin Core is the name of open source software which enables the use of this currency. ###### Usage: MEGAsync uses some files in that repository to show desktop notifications on OS X and Linux. Specifically, MEGAsync uses these files: - notificator.cpp - notificator.h - macnotificationhandler.mm - macnotificationhandler.h from this folder: https://github.com/bitcoin/bitcoin/blob/master/src/qt/ ###### License: MIT/X11 software license http://www.opensource.org/licenses/mit-license.php -------------------------------------------------------------------- #### C++ Windows Shell context menu handler (CppShellExtContextMenuHandler) https://code.msdn.microsoft.com/windowsapps/CppShellExtContextMenuHandl-410a709a Copyright (c) Microsoft Corporation. ###### Description: Example code from Microsoft for the creation of a context menu for Windows Explorer ###### Usage: This example was the base for the implementation of the shell extension of MEGAsync on Windows (MEGAShellExt project in this repository) ###### License: Microsoft Public License. https://opensource.org/licenses/MS-PL -------------------------------------------------------------------- #### QtLockedFile https://github.com/qtproject/qt-solutions/tree/master/qtlockedfile/src Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies). ###### Description: Provides locking between processes using a file. ###### Usage: MEGAsync uses this library to detect if it's already running and avoid to have several instances running at once. ###### License: The BSD 3-Clause License -------------------------------------------------------------------- #### NSPopover+MISSINGBackgroundView Copyright (c) 2015 Valentin Shergin A very tiny library that allows to access (and customize) background view of NSPopover. https://github.com/shergin/NSPopover-MISSINGBackgroundView License: MIT https://github.com/shergin/NSPopover-MISSINGBackgroundView/blob/master/LICENSE -------------------------------------------------------------------- #### QtWaitingSpinner Original Work Copyright (c) 2012-2015 Alexander Turkin QtWaitingSpinner is a highly configurable, custom Qt widget for showing spinner icons in Qt applications. https://github.com/snowwlex/QtWaitingSpinner License: MIT https://github.com/snowwlex/QtWaitingSpinner/blob/master/LICENSE -------------------------------------------------------------------- #### MEGA C++ SDK https://github.com/meganz/sdk (c) 2013-2016 by Mega Limited, Auckland, New Zealand ###### Description: MEGA --- The Privacy Company --- is a Secure Cloud Storage provider that protects your data thanks to end-to-end encryption. We call it User Controlled Encryption, or UCE, and all our clients automatically manage it. All files stored on MEGA are encrypted. All data transfers from and to MEGA are encrypted. And while most cloud storage providers can and do claim the same, MEGA is different – unlike the industry norm where the cloud storage provider holds the decryption key, with MEGA, you control the encryption, you hold the keys, and you decide who you grant or deny access to your files. This SDK brings you all the power of our client applications and let you create your own or analyze the security of our products. ###### Usage: MEGAsync uses the MEGA C++ SDK to get all functionality that requires access to MEGA servers. ###### License: Simplified (2-clause) BSD License. https://github.com/meganz/sdk/blob/master/LICENSE -------------------------------------------------------------------- #### Dependencies of the MEGA C++ SDK Due to the usage of the MEGA C++ SDK, MEGAsync requires some additional libraries.
