KeePass Password Safe 2.51.1 [Update]


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 currently known (AES and Twofish).

KeePass is really free, and more than that: it is open source (OSI certified). You can have a look at its full source and check whether the encryption algorithms are implemented correctly.

KeePass features:

  • Strong Security
  • Multiple User Keys
  • Portable and No Installation Required, Accessibility
  • Export To TXT, HTML, XML and CSV Files
  • Import From Many File Formats
  • Easy Database Transfer
  • Support of Password Groups
  • Time Fields and Entry Attachments
  • Auto-Type, Global Auto-Type Hot Key and Drag&Drop
  • Intuitive and Secure Clipboard Handling
  • Searching and Sorting
  • Multi-Language Support
  • Strong Random Password Generator
  • Plugin Architecture
  • Open Source!
