KeePass 2.48.1 Professional/ KeePass 1.39 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

  • 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.
  • 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.

    If KeePass isn't quite right for you, check out "LastPass" which I've been using for about 2 weeks and like very much.

    The best password manager for storing passwords locally and encrypted. Works perfect with Firefox and the KeeFox add-on, and it can auto-fill login forms.
