KeePass Password Safe is a free password management utility for Microsoft Windows. KeePass stores passwords, usernames, and URLs in an encrypted database unlocked by a password, key file, or a combination of the two. The database is encrypted with AES or Twofish encryption ciphers.

KeePass is maintained by Dominik Reichl. Development began in November 2003. The project is hosted on SourceForge and is currently rated "Production/Stable", and there are more than 28 translations available. There are currently several unofficial ports in development targeting Linux, Mac OS X, PocketPC, and J2ME.

Cryptography

According to the utility's author, KeePass was the first password management utility to use security-enhanced password edit controls, in this case one called CSecureEditEx.cite web

Access to the database is restricted by either a master password or a key file. Both methods may be combined to create a "composite master key". If both methods are used, then both must be present to access the password database. KeePass version 2.x will introduce a third option: dependency upon the current Windows user.cite web

KeePass encrypts the database with the AES or Twofish symmetric ciphers. AES is the default option, and Twofish is available but will be removed in version 2.x. Passwords are stored encrypted using the ARC4 cipher and a session key while in memory. The session key is derived from the user password, if used, and a salt value using the SHA-256 message digest algorithm.cite web

Portability

KeePass does not utilize any functions that require the latest Windows operating system, such as theming on XP, or relying on the .NET Framework. KeePass supports XP themes, but doesn't require this operating system capability. However, KeePass 2.x—a complete rewrite of program—is based on the .NET Framework. The application does not need to be installed, though a traditional Windows installer is available. You can download the binary ZIP package which contains only the main executable.

The program doesn't create any new registry keys and it doesn't create any initialization files (ini) in your Windows directory. Deleting the KeePass directory (in case you downloaded the binary zip package) or using the uninstaller (in case you downloaded the installer package) leaves no trace of KeePass on your system.

A password database consists of only one file that can be transferred from one computer to another easily.

There are ports to other operating systems than Windows (for example KeePassX on Mac OS X).

Features

Password management

Passwords stored by this application can be further divided into manageable groups. Each group can have an identifying icon. Groups can be further divided into subgroups in a tree-like organization.

Further, KeePass tracks the creation time, modification time, last access time, and expiration time of each password stored. Files can be attached and stored with a password record, or text notes can be entered with the password details. Each password record can also have an associated icon.

Import and export

The password list can be exported to various formats like TXT, HTML, XML and CSV. The XML output can be easily used in other applications and re-imported into KeePass using a plugin. The CSV output is fully compatible with most other password safes like the commercial closed-source Password Keeper and the closed-source Password Agent, also the CSVs can be imported by spreadsheet applications like Microsoft Excel or OpenOffice.org Calc. The HTML output uses Cascading Style Sheets (CSS) to format the table, so you can easily change the layout. Many other file formats are supported through KeePass plugins.

KeePass uses the common CSV export format of various passwords safes like Password Keeper and Password Agent. Exports from these programs can be easily imported to your KeePass databases. KeePass can parse and import TXT outputs of CodeWalletPro, a commercial closed-source password safe. It can import TXT files created by Bruce Schneier's Password Safe v2. Many other file formats are supported through KeePass plugins.

Auto-type, global hot keys, drag-and-drop

Auto-type, global auto-type hot key combination and drag-n-drop support: KeePass can minimize itself and type the information of the currently selected entry into dialogs, webforms, etc. Of course, the typing-sequence is 100% user-customizable, read the documentation file for more. KeePass features a global auto-type hot key. When KeePass is running in the background (with opened database) and you press the hot key, it looks up the correct entry and executes its auto-type sequence. All fields, title, username, password, URL and notes can be drag-n-dropped into other windows.

Intuitive and secure Windows clipboard handling: just double-click on any field of the password list to copy its value to the Windows clipboard. Timed clipboard clearing: KeePass can clear the clipboard automatically some time after you've copied one of your passwords into it. KeePass features a protection against clipboard monitors (other applications won't get notifications that the clipboard content has been changed) and it has a paste-once functionality: allow only one paste operation, after pasting the clipboard is cleared automatically by KeePass.

Browser Support

Keepass 1.x supports Mozilla Firefox and Internet Explorer, with a toolbar. Version 2.x alpha includes support for Opera browser, but there is no toolbar.

Built-in password generator

KeePass features a built-in password generator that generates random passwords. Random seeding can be done through user input (mouse movement and random keyboard input).

Plugins

KeePass has a plugin architecture. There are already some plugins available on the KeePass homepage (import/export from/to various other formats, plugin checking for updates, database backup plugin, etc.). Note that plugins may compromise the security of KeePass.
