Exploring the Features of KeePass Password Manager

KeePass is a free open source password manager, which helps you to manage your passwords securely. 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.

Exploring the Features of KeePass Password Manager

KeePass makes use of the frequent CSV export format of varied password safes like Password Keeper and Password Agent. Exports from these programs might be simply imported to your KeePass databases. The password list might be exported to formats like TXT, HTML, XML, and CSV.

The application has a portable edition: you may carry it on a USB stick and run it on Windows systems without installation.

Strong Security

  • KeePass supports the Advanced Encryption Standard (AES, Rijndael) and the Twofish algorithm to encrypt its password databases. Both of those ciphers are thought to be very safe. AES e.g. grew to become efficient as a U.S. Federal authorities standard and is authorized by the National Security Agency (NSA) for high secret information.
  • The full database is encrypted, not solely 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 safe one-way hash function. No assaults are recognized but towards SHA-256. The output is remodeled using a key derivation function.
  • Protection towards dictionary and guessing assaults: by remodeling the master key part hash using a key derivation function (AES-KDF, Argon2, …), dictionary and guessing assaults might be made more durable.
  • 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 interior XML format, passwords are encrypted using a session key.
  • Security-enhanced password edit controls: KeePass is the primary password manager with security-enhanced password edit controls. None of the available password edit control spies work towards these controls. The passwords entered in these controls aren’t even seen within the process memory of KeePass.
  • The master key dialog might be proven on a safe desktop, on which just about no keylogger works. Auto-Type might be protected towards keyloggers, too.

  • Added ‘Mark Entry for Comparison’ and ‘Compare Entry with Marked Entry’ commands (in the main menu ‘Entry’ → ‘Compare’); these two commands support comparing two entries that are stored in different databases (opened in tabs).
  • Report dialogs can now be closed by pressing the ESC key.

  • The increased default number of AES-KDF iterations.
  • Improved syntax highlighting for {CLIPBOARD-SET:…} placeholders (in the auto-type item editing dialog).
  • The node mode of the configuration element ‘/Configuration/Meta/PreferUserConfiguration’ is now ‘None’ by default.
  • Improved INI loading performance.
  • Improved data size formatting.
  • Renamed value columns/commands in the history entry comparison dialog from ‘A’/’B’ to ‘1’/’2′.
  • Improved process memory protection of history entry comparisons.
  • Improved process memory protection of ‘CryptoRandomStream’ objects.
  • Improved thread safety of process memory protection on Unix-like systems.
  • The MSI file is now built using Visual Studio 2022.
  • Various UI text improvements.
  • Various code optimizations.
  • Minor other improvements.
