Developer Tools

13. MCrypt

This replacement for the old Unix crypt command gives developers an easy way to add encryption to their code. It can protect files or data streams and supports 22 different algorithms. Operating System: Windows, Linux, Unix, BSD.

14. Crypto++

Crypto++ is a free library of cryptography tools for C++. It includes dozens of algorithms, password-based key derivation functions, a prime number generator, and much more. Operating System: OS Independent.

15. Jasypt

If you need to add encryption to your code, but don't have a deep understanding of cryptography, Jasypt is for you. It uses high-security, standards-based encryption techniques that allow you to encrypt passwords, texts, numbers, and more. Operating System: OS Independent.


16. JCrypTool

Want to learn more about encryption and cryptography? JcrypTool is an Eclipse-based e-learning tool that makes it easy to experiment with various encryption mechanisms and learn more about how they work. Operating System: OS Independent.


17. TrueCrypt

TruCrypt can encrypt a single file, an entire drive, or a partition. It can also create virtual encrypted disks or encrypt portable hard drives and USB flash drives. Operating System: Windows, Mac, Linux.

18. AxCrypt

AxCrypt makes encrypting files extremely easy for Windows users. You simply open Windows Explorer, right-click files, and you're done. Operating System: Windows.

19. DiskCryptor

DiskCryptor performs similar functions as TrueCrypt, but has a less restrictive license. The project home page is not in English, but the link here will take you to the English part of the site. Operating System: Windows.

20. a href="">Encrypt

Designed to be as lightweight as possible, Encrypt is easy to use and offers strong encryption. Operating System: Windows, Linux, Unix.

File Transfer

21. WinSCP

Need to transfer files securely? WinSCP supports SFTP, as well as FTP and SCP. Operating System: Windows.

File Sharing

22. RetroShare With RetroShare, you set up your own network simply by sending your friends a key. Chats and file transfers are encrypted by OpenSSL to protect your privacy. Operating System: Windows, Linux, Unix, BSD.

23. MUTE

Unlike other P2P networks, this anonymous network avoids all direct connections between sharing partners. Inspired by the behavior of ants, MUTE routes traffic through several nodes, making it much more difficult to track. Operating System: OS Independent.

24. Kommute

This P2P file-sharing client offers an alternate front-end for accessing the MUTE network. Key features include multi-source downloads, swarming, and two-level search. Operating System: Windows, Linux.

25. StealthNet Web-UI

This project provides an interface to the anonymous StealthNet P2P network (formerly known as Rshare Community Edition). The Web site also links to a Wiki for helpful tips on how to configure the program for maximum privacy. Operating System: OS Independent.
