KeePass 2.59 / KeePass 1.43 Classic

KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database.

The databases are encrypted using the best and most secure encryption algorithms. A password database consists of only one file that can be transferred from one computer to another easily.

KeePass supports the Advanced Encryption Standard (AES, Rijndael) and the Twofish algorithm to encrypt its password databases.

Both of these ciphers are regarded as being very secure. AES e.g. became effective as a U.S. Federal government standard and is approved by the National Security Agency (NSA) for top secret information.

KeePass All Features:

KeePass uses the common CSV export format of various passwords safes like Password Keeper and Password Agent. Exports from these programs you can be easily import to your KeePass databases. The password list you can be export to various formats like TXT, HTML, XML and CSV.

The application has portable edition: you can carry it on an USB stick and runs on Windows systems without installation.

Strong Security

• The app supports the Advanced Encryption Standard (AES, Rijndael) and the Twofish algorithm to encrypt its password databases. Both of these ciphers are regarded as being very secure. AES e.g. became effective as a U.S. Federal government standard and is approved by the National Security Agency (NSA) for top secret information.
• The complete database is encrypted, not only the password fields. So, your user names, notes, etc. are encrypted, too.
• SHA-256 is used to hash the master key components. SHA-256 is a 256-bit cryptographically secure one-way hash function. No attacks are known yet against SHA-256. The output is transformed using a key derivation function.
• Protection against dictionary and guessing attacks: by transforming the master key component hash using a key derivation function (AES-KDF, Argon2, …), dictionary and guessing attacks can be made harder.
• Process memory protection: your passwords are encrypted while KeePass is running, so even when the operating system dumps the KeePass process to disk, your passwords aren’t revealed.
• [2.x] Protected in-memory streams: when loading the inner XML format, passwords are encrypted using a session key.
• Security-enhanced password edit controls: KeePass is the first password manager that features security-enhanced password edit controls. None of the available password edit control spies work against these controls. The passwords entered in those controls aren’t even visible in the process memory of KeePass.
• The master key dialog can be shown on a secure desktop, on which almost no keylogger works. Auto-Type can be protected against keyloggers, too.

Changes in KeePass 1.59 Professional:

New features:

• On Windows 11 24H2 ARM64 and later, KeePass now runs natively, too (i.e. without x64 emulation).
• Added KeePassLibN native support library, which provides native implementations of AES-KDF and Argon2 on Windows systems (x86, x64 and ARM64).
• New C# AES-KDF implementation (about 30-50 times as fast as before, depending on the system; used when the native support library is unavailable or disabled).
• New C# KDB import/export module, which now makes it possible to import/export KDB files on ARM64 systems and on Unix-like systems, too.
• The KDB import/export module now supports importing and exporting the default user name and the database color.
• When exporting a database to a KDB file, the root group is now exported, too.
• The ‘About KeePass’ dialog now displays the architecture of the current process (‘x86’/’x64’/’ARM64’/… instead of only ’32-bit’/’64-bit’).
• Added support for opening URLs with Maxthon, SeaMonkey and Yandex in private mode.
• On Unix-like systems, URLs in certain views are now linkified.
• Some development snapshots can now load DLL plugins.
• Added framework-specific solution and project files for Visual Studio 2022.

Improvements:

• Encrypting/decrypting databases using the AES algorithm is now faster.
• The option for using the native support library now also applies to Argon2.
• Native support library settings are now respected when using KeePass as a library (e.g. KPScript or PowerShell script).
• When clicking the [OK] button of the options dialog, volatile settings (such as the main window position/size) are now saved, too.
• When an exception occurs while exporting data, it is now shown in the status logger dialog, if one is displayed.
• Improved formatting of multiline messages in the status logger dialog.
• The KDB import/export module now refuses to use a master key containing an XML key file (because KeePass 1.x does not support XML key files).
• The KDB export module does not export unnecessary auto-type sequence definitions anymore.
• Improved removal of dangling custom icon references.
• The app is now built using Visual Studio 2022.
• Increased target framework version.
• Improved efficiency of some algorithms that use a set.
• Improved creation of AES CSP objects.
• Improved project cleanup script.
• Removed KeePassLibC native support library (because it is not used by KeePass 2.x anymore; KeePassLibC continues to be available in the KeePass 1.x source code package); the installer deletes it when updating an existing app installation.
• Installer: updated native image (NGen) size estimation.
• Upgraded installer.
• Various UI text improvements.
• Various code optimizations.
• Minor other improvements.

Bugfixes:

• The ‘Test’ button on the ‘Security’ tab page of the database settings dialog does not ignore the option for using the native support library anymore.
• The KDB import module does not append a new-line character to notes anymore.

Changes in KeePass 1.43 Classic:

New Features:

• Added option ‘Prevent certain screen captures’ (in ‘Tools’ → ‘Options’ → tab ‘Advanced’, turned off by default); note that this may also prevent legitimate other software (remote desktop solutions, accessibility tools such as screen magnifiers, etc.) from seeing KeePass windows.
• Added {PASSWORD_ENC} placeholder, which is replaced by the password of the current entry in encrypted form (DPAPI/CryptProtectData).
• Added ‘-pw-enc:‘ command line parameter.

Improvements:

• Improved database save confirmation dialog text.
• Improved behavior of the translation system for untranslatable strings.
• Improved project cleanup script.
• Upgraded installer.
• Various UI text improvements.
• Various code optimizations.
• Minor other improvements.

Bugfixes:

• Fixed a Windows version detection bug.
