KeePass Screenshot Language: multi-language support (more than 40 languages). System requirements: Windows 7 / 8 / 10 / 11 / Mono (Linux, MacOS, ...).

Today, you have to remember many passwords. You need a password for a lot of websites, your e-mail account, your webserver, network logins, etc. The list is endless. Also, you should use a different password for each account, because if you would use only one password everywhere and someone gets this password, you would have a problem: the thief would have access to all of your accounts.

KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can store all your passwords in one database, which is locked with a master key. So you only have to remember one single master key to unlock the whole database. Database files are encrypted using the best and most secure encryption algorithms currently known (AES-256, ChaCha20 and Twofish). For more information, see the features page.

Some of the key features of KeePass:

  • Highly encrypted databases.
  • Support of master passwords and key files.
  • Runs on all Windows operating systems and Mono (Linux, MacOS, ...), and does not need to be installed.
  • Export password list to various formats (TXT, HTML, XML, CSV, ...).
  • Import from many formats.
  • Easy database transfer.
  • Support of password groups.
  • Time fields support.
  • Auto-Type, global auto-type hot key and drag-n-drop support.
  • Copy fields to the system clipboard.
  • Searching and sorting.
  • Multi-language support.
  • Strong random password generator.
  • Low memory requirement.
  • Open source!

KeeGen Screenshot Language: English German. System requirements: Windows 10 or higher.

KeeGen is a password generator app that supports various generation methods and options.

  • Generation based on character sets: define the length and characters that generated passwords should consist of.
  • Generation based on patterns: allows to generate passwords that follow complex rules.
  • Various options like enforcing that each character must occur at most once, excluding look-alike characters, etc.
  • Generate a password or a password list (multiple passwords at once).
  • Passwords can be copied to the clipboard.
  • Passwords can be transferred to other apps using drag-and-drop.
  • Passwords can be saved to a file (various formats, including TXT, CSV and HTML).
  • Passwords can be shared with other apps.
  • Settings can be saved as profiles.
  • KeeGen collects entropy from various sources and uses a cryptographically secure random number generator (based on SHA-256 and ChaCha20).
  • Works without Internet connection.
KeeGen is available in the Windows app store: KeeGen App Store Page.

ReHash is an easy-to-use console-based hash calculation tool written in standard C++. It may be freely distributed and modified under the terms of the BSD open source license.

The tool is compilable under Windows and Linux.

It supports many algorithms, for example Adler32, CRC-16, CRC-16-CCITT, CRC-16-XMODEM, CRC-32, ELF-32, FCS-16, FCS-32, FNV-32, FNV-64, GHash-32-3, GHash-32-5, GOST-Hash, HAVAL (3/4/5, 256), MD2, MD4, MD5, SHA-1, SHA-256, SHA-384, SHA-512, Size64, Tiger, XUM32. For a full list see the ReHash documentation manual (included in downloadable package).

It is possible to compute HMACs of all algorithms.

The tool can output the hashes in various formats like plain text, HTML, XML and CSV.

ReHash can be fully configured using some of the many command line arguments which can be passed to the tool. You can selectively activate/disable hash algorithms and set scanning options like scanning subdirectories recursively and excluding/including files using advanced file pattern matching.

Language: neutral. System requirements: C++ compiler.

CSHA1 is a C++ class implementation of the US Secure Hash Algorithm 1 as defined in the FIPS PUB 180-1 standard.

SHA-1 is a very secure hash algorithm, which has been designed by the NIST along with the NSA. It produces a 160-bit hash value, and therefore is more collision-resistant and resistant against birthday-attacks than MD5 or MD2 for example.

New in version 2.1:
  • Deconstructor (resetting internal variables) is now only implemented if SHA1_WIPE_VARIABLES is defined (which is the default).
  • Renamed inclusion guard to contain a GUID.
  • Demo application is now using C++/STL objects and functions.
  • Unicode build of the demo application now outputs the hashes of both the ANSI and Unicode representations of strings.
  • Various other demo application improvements.

BlakeSharp is an implementation of the BLAKE hash algorithm.

Language: neutral. System requirements: MFC / C++ compiler.

Secure Password Edit controls are resistant to window style changers and programs that read out the text of password edits.

New in version 1.3:
  • CSecureEdit is now distributed under a BSD-style license.
  • In Unicode builds, CSecureEdit now uses a dot as password masking character.
  • The password control style is now set (when the user tries to copy data out of the control, Windows shows a failure tooltip).
  • Added ability to accept text drops.
  • The password can now be retrieved using the GetRealText method (instead of directly accessing the internal m_strRealText variable).
  • Improved change detection logic and performance of mask string building.
  • Updated project files for Visual Studio 2008.
  • Added support for Aero theming in the demo application.
  • Minor other code improvements.

Language: neutral. System requirements: MFC / C++ compiler.

Improved version of the CSecureEdit class, but also has some additional limitations (no selections are possible). The CSecureEditEx class is, in contrast to the lite CSecureEdit class, resistant against process memory dumpers. The entered passwords aren't visible in the process memory of the application.

Language: Neutral. System requirements: Windows.

This library securely encrypts and decrypts files. It uses the Advanced Encryption Standard (AES) and SHA-256 algorithms. KeeCryptLib attempts to make dictionary-attacks a bit harder by encrypting the master key multiple times before using it (this adds a linear time factor). In order to generate the IVs and master seeds, it collects various more or less random things from Windows (mouse cursor position, time, memory status, etc.).

KeeCryptLib is distributed under the terms of the BSD license. Feel free to use the library in your project (the API is pretty simple, have a look at it!).
