KeePass是一個高度安全和受歡迎的開源密碼管理器，用於以安全的方式存儲和管理密碼、用戶名和其他敏感信息。它由Dominik Reichl開發，適用於包括Windows、macOS、Linux和移動設備在內的各種平台。

KeePass 的其中一個主要特點是其強大的安全性。它採用了強加密算法（例如，AES, Twofish）來保護存儲的數據，確保只有擁有主密碼的授權用戶才能訪問他們的密碼。主密碼作為解鎖加密數據庫的主要密鑰。

KeePass 提供了用戶友好的界面，允許用戶使用文件夾和類別以結構化的方式組織密碼。此外，它還提供了密碼生成工具，幫助用戶創建複雜且獨特的密碼以增強安全性。

該軟體使用戶能夠快速搜尋特定密碼，並提供自動輸入等功能，允許自動填寫網站和應用程式的登錄表單。KeePass 還支援插件，擴展其功能並使其可自訂以滿足個人需求。

此外，KeePass 通過允許用戶將其加密的密碼數據庫存儲在各種存儲媒介上，例如本地磁碟、USB 驅動器或雲端存儲，強調了可攜性和可訪問性。這使得用戶能夠在不同設備上存取他們的密碼，同時保持安全和隱私。

總體而言，KeePass 是一個可靠且安全的密碼管理解決方案，有助於用戶整理和保護其敏感信息。

• Added menu/toolbar styles, freely selectable in \'Tools\' -> \'Options\' -> tab \'Interface\'; available styles are \'Windows 10\', \'Windows 8.1\', \'KeePass - Gradient\', \'.NET/Office - Professional\' and \'System - Classic\'; by default KeePass uses the style most similar to the one of the current operating system.
• Refined application icons (thanks to Victor Andreyenkov).
• Auto-Type: new target window classification method, which improves compatibility with target windows hosted within other windows (e.g. a PuTTY window within SuperPuTTY/MTPuTTY).
• Auto-Type: added workaround for the default Ctrl+Alt behavior of KiTTY variants (which differs from Windows\' behavior).
• Before clearing the clipboard, KeePass now first copies a non-sensitive text into it; this ensures that no sensitive information remains in the clipboard even when clearing is prevented by the environment (e.g. when running in a virtual machine, when using a clipboard extension utility, ...).
• Added support for opening entry URLs with Internet Explorer or Google Chrome in private mode via the context menu -> \'URL(s)\' -> \'Open with ... (Private)\'.
• Added URL override suggestions for Internet Explorer and Google Chrome in private mode in the URL override suggestions drop-down list in the entry dialog.
• Added optional built-in global URL overrides for opening HTTP/HTTPS URLs with Internet Explorer or Google Chrome in private mode.
• Added Ctrl+K shortcut for the \'Duplicate Entry\' command.
• Mozilla Bookmarks HTML import: added support for importing tags.
• Added support for exporting to Mozilla Bookmarks HTML files.
• Windows/IE favorites export: entry fields are Spr-compiled now, and entries with cmd:// URLs are now exported as LNK files.
• HTML export/printing: added support for UUIDs, added horizontal lines between entries in details mode, added background color for group headings, long field names are hyphenated now, and long field data now breaks and wraps onto the next line.
• Plugins: added possibility to configure file transactions for each URI scheme.
• Plugins: added possibility to provide custom \'Save As\' dialogs more easily.
• Converted some PNG images as a workaround for a problem in Cairo/LibPNG on Unix-like systems.
• As a workaround for a weakness in Mono\'s FileDialog, before showing such a dialog on Unix-like systems KeePass now tries to load the file \'~/.recently-used\' and deletes it, if it is not a valid XML file.
• KPScript: added support for specifying the master password in encrypted form using the \'-pw-enc:\' command line parameter (exactly like in KeePass, compatible with the {PASSWORD_ENC} placeholder).
• KPScript: the \'Export\' command now supports the optional \'-GroupPath:\' parameter (to export a specific group instead of the whole database).
• KPScript: the \'GetEntryString\' command now supports the \'-FailIfNoEntry\' option.
• KPScript: added \'-refx-Expires\' and \'-refx-Expired\' entry identification parameters.
• KPScript: the \'Import\' command now prints more specific error messages.
• All KeePass program binaries are now dual signed using SHA-1 and SHA-256.

• Auto-Type: improved keyboard layout handling when the target window changes during an auto-type process.
• Auto-Type: improved compatibility with Remote Desktop Connection client and VirtualBox.
• Improved icon recoloring.
• Improved printing of dates/times and tags.
• The password generator based on a character set now ensures that the generated password is Spr-invariant.
• Password generator based on a pattern or a custom algorithm: when a Spr-variant password is generated, a confirmation dialog for accepting this password is displayed.
• If the \'Save Database\' policy prevents saving, the auto-save option is now ignored.
• Improved .NET Framework version detection.
• PLGX debugging: when the command line option \'-debug\' is passed and a PLGX plugin fails to compile, the output of all tried compilers is saved to a temporary file.
• Improved file transaction creation time handling on Unix-like systems.
• Improved compatibility with Mono on BSD systems.
• Enhanced PrepMonoDev.sh script for compatibility with Mono 4.x.
• Removed KeePassLibSD sub-project (a KeePass library for Pocket PC / Windows Mobile) from the main solution.
• Upgraded installer.
• Various code optimizations.
• Minor other improvements.

• When running under Mono (Linux, Mac OS X, ...), two options related to window minimization are disabled now (because they do not work properly due to a Mono bug).
