VeraCrypt version 1.17 Beta 19

VeraCrypt 是一套老牌的磁碟加密工具，主打「即時加密」技術：資料在寫入前自動加密、讀取時自動解密，全程不需手動介入。它能建立加密的虛擬磁碟或加密整個系統分割區，連檔案名稱、資料夾結構、剩餘空間與中繼資料都一併保護，沒有正確的密碼或金鑰就無法讀取任何內容。這套開源軟體長期維護，更新頻率穩定，在同類安全工具中屬於口碑扎實的熱門選擇，尤其受到重視隱私的使用者信賴。

它適合需要保護機密文件、隨身碟資料或整台電腦系統的人，無論是個人隱私或工作機密，都能透過加密磁碟來隔離風險。與 Folder Lock 或 Comodo 等整合型安全套件相比，VeraCrypt 功能更專注、沒有多餘的防毒或防火牆，但相對需要一些基本概念才能上手。目前僅提供英文介面，Windows 與 macOS 都有對應版本，採開源授權可免費使用；若需要中文介面，可能得搭配其他語系包或自行熟悉操作，下載前建議先確認自己的需求與平台相容性。

VeraCrypt is a great application to establish and maintain an on-the-fly-encrypted volume. On-the-fly encryption means that data is automatically encrypted right before it is saved and decrypted right after it is loaded, without any user intervention. This is a very secure method of data encryption as any data that is stored on an encrypted volume cannot be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. The entire file system is encrypted (e.g. file names, folder names, contents of every file, free space, meta data, etc) to give you as much security as possible.

Key features include:

• Easy to use interface.
• Lightweight.
• Enhanced security.

VeraCrypt is a free disk encryption software based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. VeraCrypt has been specifically designed to give you better security with the data you want to encrypt. It is relatively lightweight, and has an easy to use interface.

* All OSs:
- Support UNICODE passwords: all characters are now accepted in passwords (except Windows system encryption)
- Cut mount/boot time by half thanks to a clever optimization of key derivation (found by Xavier de Carné de Carnavalet)
- Optimize Whirlpool code by using assembly (25% speed gain compared to previous code).
- Add support for creating exFAT volumes.
- Include new icons and graphics contributed by Andreas Becker (http://www.andreasbecker.de)
* Windows:
- Fix dll hijacking issue affecting installer that allows code execution with elevation of privilege (CVE-2016-1281). Reported by Stefan Kanthak (http://home.arcor.de/skanthak/)
- Sign binaries using both SHA-1 and SHA-256 to follow new Microsoft recommendations.
- Solve issues under Comodo/Kaspersky when running an application from a VeraCrypt volume (Reported and fixed by Robert Geisler)
- Bootloader: Protect password/PIM length by filling the fields to maximum length with '*' after ENTER
- Solve issue with system favorites not being able to be mounted to drive A:
- Solve lost focus issues for after displaying the waiting dialog
- Implement PIM caching, for both system encryption and normal volumes. Add options to activate it.
- Internal rewrite to make VeraCrypt native UNICODE application.
- Workaround to avoid false positive detection by some anti-virus software.
- Add GUI indicator for the amount of randomness gathered using mouse movement.
- Hide disconnected network drives in the list of available drives. Add option to make them available for mounting.
- Solve issue that caused in some cases configuration and history XML files to be updated even when not needed.
- Fix leak of path of selected keyfiles in RAM.
- Fix TB unit can't be deselected in VeraCryptExpander.
- Add Alt+i keyboard shortcut for "Use PIM" checkbox.
- Minor GUI and translations fixes.
* Linux/MacOSX:
- Fix issue of --stdin option not handling correctly passwords that contain a space character (reported and fixed by Codeplex user horsley1953).
- Fix issue creating volumes using command line with a filesystem other than FAT.
- Support K/M/G/T suffixes for --size switch to indicate unit to use for size value.
