Cryptlib by Peter Gutmann is a security toolkit that allows even less experienced programmers to add strong encryption and authentication services to their programs, security features that are becoming more and more indispensable.
The library attempts to hide the low-level details of encryption/decryption and authentication from programmers, allowing them to quickly make their projects more secure.
Some of the symmetric encryption (private key) and authentication algorithms that cryptlib supports include the following:
- AES (Rijndael)
- Blowfish
- DES, 3DES
- RC2, RC4, RC5
The following hash algorithms are available in the library:
- MD2, MD4, MD5
- RIPEMD-160
- SHA
It offers services such as:
- S/MIME
- SSL/TLS
- ssh
It features various hashed message authentication code algorithms:
- HMAC-MD5, HMAC-SHA, HMAC-RIPEMD-160
Finally, asymmetric (public/private key) encryption algorithms such as the following are available:
- Diffie-Hellman, DSA, RSA
cryptlib can also be used with a variety of crypto devices (for example, Fortezza cards and Smart cards).
cryptlib contains as core components implementations of the most popular encryption and authentication algorithms, AES, Blowfish, CAST, DES, triple DES, IDEA, RC2, RC4, RC5, and Skipjack conventional encryption, MD2, MD4, MD5, RIPEMD-160 and SHA hash algorithms, HMAC-MD5, HMAC-SHA, and HMAC-RIPEMD-160 MAC algorithms, and Diffie-Hellman, DSA, Elgamal, and RSA public-key encryption.
In addition to these built-in capabilities, cryptlib can make use of the crypto capabilities of a variety of external crypto devices such as hardware security modules (HSMs), Fortezza cards, PKCS #11 devices, and crypto smart cards. The crypto device interface also provides a convenient general-purpose plug-in capability for adding new functionality which will be automatically used by cryptlib.
The library is free if used in personal, freeware, or shareware projects. The library is written in C. ActiveX and C++ wrappers are provided. The project is OSI Certified Open Source Software.
Enhancements:
- The final release contains mostly minor tweaks based on user feedback from the 3.1 final betas, with no noticeable external changes. Internally, the HTTP engine has been significantly improved, TLS 1.1 is now supported (although at release time there were no other known implementations of this to test against), the BeOS port has been re-done to handle the current state of the OS
using GNU development tools instead of the original Be ones (thanks to Simon Taylor for providing access to his system to do the work on), and the perpetual tweaking of the networking subsystem to handle OS-specific quirks has continued.

Enhancements:

KeePass Password Safe Portable 1.16 is a powerful tool that allows you to manage your passwords in a secure way.

Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your homepage's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, homepage, etc. Unimaginable.
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).

Major Features:

1. Strong Security
   • KeePass supports the Advanced Encryption Standard (AES, Rijndael) and the Twofish algorithms to encrypt its password databases.
   • Both of these ciphers are regarded as very secure by the cryptography community. Banks are using these algorithms for example, too.
   • Even if you would use all computers in the world to attack one database, decrypting it would take longer than the age of the universe.
   • Even quantum computers won't help that much. The algorithms are symmetric so its complexity would be reduced a bit, anyway, the sun will go nova before you have decrypted the database.
   • The complete database is encrypted, not only the password fields. So your usernames, notes, etc. are protected, too.
   • SHA-256 is used as password hash. SHA-256 is a 256-bit cryptographically secure one-way hash function. Your master password is hashed using this algorithm and its output is used as key for the encryption algorithms.
   • In contrast to many other hashing algorithms, no attacks are known yet against SHA-256.
   • Protection against dictionary and guessing attacks: by transforming the final master key very often, dictionary and guessing attacks can be made harder.
   • In-Memory Passwords Protection: Your passwords are encrypted while KeePass is running, so even when the operating system caches the KeePass process to disk, this wouldn't reveal your passwords anyway.
   • [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.
   • Also see the security information page.
2. Key Multiple User Keys
   • One master password decrypts the complete database.
   • Alternatively you can use key files. Key files provide better security than master passwords in most cases. You only have to carry the key file with you, for example on a floppy disk, USB stick, or you can burn it onto a CD. Of course, you shouldn't lose this disk then.
   • For even more security you can combine the above two methods: the database then requires the key file and the password in order to be unlocked. Even if you lose your key file, the database would remain secure.
   • [2.x] Additionally, you can lock the database to the current Windows user account. The database can then only be opened by the same person who created it.
   • Also see keys information page.
3. Features Portable and No Installation Required, Accessibility
   • KeePass is portable: it can be carried on an USB stick and runs on Windows systems without being installed.
   • Installer packages are available, too, for the ones who like to have shortcuts in their Windows start menu and on the desktop.
   • KeePass doesn't store anything on your system. The program doesn't create any new registry keys and it doesn't create any initialization files (INI) in your Windows directory. Deleting the KeePass directory (in case you downloaded the binary ZIP package) or using the uninstaller (in case you downloaded the installer package) leaves no trace of KeePass on your system.
   • [1.x] KeePass runs, without downloading any additional libraries, on Windows 98, 98SE, ME, NT, 2000, XP (Home & Pro, 32-bit & 64-bit), 2003 and Vista. No .NET framework is required.
   • All Windows Systems1
   • [2.x] KeePass requires the Microsoft .NET Framework (which can be downloaded for free at Microsoft's website) or Mono. Windows Vista already includes the .NET framework; for Windows 98 / ME / 2000 / XP you need to install it, if it's not installed already. With Mono, KeePass also runs on Linux, Mac OS X, BSD, etc.
   • Ports for other systems like Linux, Mac OS X, PocketPC, Smartphone, etc. are available! See the downloads page.
   • [2.x] Accessibility: KeePass 2.x features an advanced option that explicitly optimizes the user interface for screen readers.
4. Export Export To TXT, HTML, XML and CSV Files
   • The password list can be exported to various formats like TXT, HTML, XML and CSV.
   • The XML output can be easily used in other applications.
   • The HTML output uses cascading style sheets (CSS) to format the table, so you can easily change the layout.
   • The CSV output is fully compatible with most other password safes like the commercial closed-source Password Keeper and the closed-source Password Agent, also the CSVs can be imported by spreadsheet applications like Microsofts Excel or OpenOffice's Calc.
   • Many other file formats are supported through KeePass plugins.
5. Import Import From Many File Formats
   
   • KeePass uses the common CSV export format of various passwords safes like Password Keeper and Password Agent. Exports from these programs can be easily imported to your KeePass databases.
   • KeePass can parse and import TXT outputs of CodeWalletPro, a commercial closed-source password safe.
   • KeePass can import TXT files created by Bruce Schneier's Password Safe v2.
   • [2.x] Out of the box, KeePass supports importing more than 25 formats (see Help: Import).
   Many other file formats are supported through KeePass plugins.
   
6. Message Easy Database Transfer
   A password database consists of only one file that can be transferred from one computer to another easily.
   
7. Multiple Support of Password Groups
   
   • You can create, modify and delete groups, in which passwords can be sorted into.
   • The groups can be arranged as a tree, so a group can have subgroups, those subgroups can have subgroups themselves, etc.
   • Also see this screenshot.
8. Time Fields and Entry Attachments
   
   • KeePass supports time fields: creation time, last modification time, last access time and expiration time.
   • You can attach files to password entries (useful to store PGP signature files in KeePass for example).
   • [2.x] KeePass has a powerful internal viewer for text files, images and documents. You don't even need to export attached files to view them!
9. Auto-Type, Global Auto-Type Hot Key and Drag&Drop
   • KeePass can minimize itself and type the information of the currently selected entry into dialogs, webforms, etc. Of course, the typing-sequence is 100% user-customizable, read the documentation file for more.
   • KeePass features a global auto-type hot key. When KeePass is running in the background (with opened database) and you press the hot key, it looks up the correct entry and executes its auto-type sequence.
   • All fields, title, username, password, URL and notes can be drag&dropped into other windows.
10. Binary Intuitive and Secure Windows Clipboard Handling
    
    • Just double-click on any field of the password list to copy its value to the Windows clipboard.
    • Timed clipboard clearing: KeePass can clear the clipboard automatically some time after you've copied one of your passwords into it.
    • [1.x] Protection against clipboard monitors (other applications won't get notifications that the clipboard content has been changed).
    • [1.x] Paste-once functionality: allow only one paste operation, after pasting the clipboard is cleared automatically by KeePass.
11. Magnifier Searching and Sorting
    
    • You can search for specific entries in the databases.
    • To sort a password group, just click on one of the column headers in the password list, you can sort by any column.
12. Translation Multi-Language Support
    
    • KeePass can be translated into other languages very easily.
    • Over 30 different languages are available!
    • See the translations page.
13. Key Strong Random Password Generator
    
    • KeePass can generate strong random passwords for you.
    • You can define the possible output characters of the generator (number of characters and type).
    • Random seeding through user input: mouse movement and random keyboard input.
14. Plugin Architecture
    
    • Other people can write plugins for KeePass.
    • Plugins can extend the functionality of KeePass, like providing additional import/export methods for other file formats.
    • Go to the plugins page for more information and plugin downloads.
15. Open Source!
    
    • KeePass free and you have full access to its source code!
    • Open Source prevents backdoors. You can have a look at its source code and compile it yourself.
    • You can yourself check if the security is implemented correctly, you can, if you want, use any other encryption algorithm.
    • Opening the sources also encourages other people to port the application to other systems (PocketPC version already in development) or write translations.
    • KeePass is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative.

Enhancements:

1. New Features:
   • Added option to use Windows' CNG/BCrypt API for key transformations (about 50% faster than the KeePass built-in key transformation code; by increasing the amount of rounds by 50%, you'll get the same waiting time as in 1.15, but the protection against dictionary and guessing attacks is raised by a factor of 1.5; option enabled by default; only Windows Vista and higher).
   • Completely new update checking system that now also supports checking for new plugin versions.
   • Added warning when trying to open a KDBX file created by KeePass 2.x (with hint about how to migrate from 2.x to 1.x).
   • Added 'KeeAutoNewDbBasePath' and 'KeeAutoNewDbBaseName' configuration options (to specify the default location where the database file will be stored in mini mode).
   • Added advanced option to immediately delete TAN entries after using them.
   • Added '-minimize' command line option.
   • Added '-registerfileext' and '-unregisterfileext' command line options to register/unregister the KDB file association.
   • File association methods are now UAC aware.
   • Added check for reserved group names (like 'Backup').
   • On Windows Vista and higher, core database manager error / warning messages are displayed using modern task dialogs.
   • The number of days below which entries are treated as soon to expire can now be configured (see help -> customize).
   • Plugins: added new COM interface (IKpAPI2) for the main API that allows querying whether the database is the one initially specified on the command line.
   • Key provider plugin API: new key query method that supports context information.
2. Improvements:
   • Image list handling improvements.
   • When auto-locking after the specified number of seconds of inactivity, KeePass minimizes to taskbar or to tray, depending on the 'Minimize to tray instead of taskbar' option.
   • Plugin versions are now displayed in a separate column in the plugins dialog.
   • When trying to open a second master key dialog or auto-type entry selection dialog for a window, KeePass brings itself to the foreground instead of showing a second dialog.
   • Calculation of soon to expire entries is now more precise.
   • Various improvements to status bar messages.
   • Improved workspace locking toolbar button tooltips.
   • Installer: various minor improvements.
