KeePass是一个高度安全且受欢迎的开源密码管理器，用于以安全的方式存储和管理密码、用户名和其他敏感信息。它由Dominik Reichl开发，可用于包括Windows、macOS、Linux和移动设备在内的各种平台。

KeePass的一个关键功能是其强大的安全性。它使用强加密算法（例如，AES，Twofish）来保护存储的数据，确保只有拥有主密码的授权用户可以访问他们的密码。主密码作为解锁加密数据库的主要密钥。

KeePass提供了一个用户友好的界面，允许用户使用文件夹和类别以结构化的方式组织密码。此外，它提供了密码生成工具，帮助用户创建复杂且独特的密码以增强安全性。

该软件使用户能够快速搜索特定密码，并提供自动填充等功能，可以自动填写网站和应用程序的登录表单。KeePass 还支持插件，扩展其功能并使其可定制以满足个人需求。

此外，KeePass通过允许用户将其加密的密码数据库存储在各种存储介质上，如本地驱动器、USB驱动器或云存储，从而强调了便携性和可访问性。这使用户能够在不同设备上访问其密码，同时保持安全性和隐私性。

总体来说，KeePass 是一个可靠且安全的密码管理解决方案，可以帮助用户整理和保护敏感信息。

关键特性：

• 密码生成器：创建强且随机的密码。
• 组织密码将密码分类为组和子组。
• 搜索与筛选快速查找特定条目。
• 自定义字段: 向条目添加额外信息。

• 安全功能: 提供额外的安全选项。
• 跨平台: 可在各种操作系统上访问。
• 插件和扩展程序通过添加附加功能来扩展功能。
• 进出口轻松导入/导出密码。
• 数据库同步: 安全地跨设备同步数据库。

• 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).
