Encryption tools

Times are changing and spying has become a common phenomenon everywhere. There have been increasing instances where even the governments have been found to be spying on their citizens from time to time. This is one of the prime reasons why the importance of Encryption has increased manifold. Encryption tools are very important because they keep the data safe by encrypting it so that even if someone accesses the data, they can’t get through the data unless they know how to decrypt the data. These tools use algorithm schemes to encode the data to prevent unauthorized access to the encrypted data.
Some of the popular Encryption Tools will be discussed in this article.


TrueCrypt is open source encryption tool which can encrypt a partition in the Windows environment (except Windows 8); it’s equipped for creating a virtual encrypted disk in a file. Moreover, it has the capability to encrypt the complete storage device. TrueCrypt can run on different operating systems like Linux, Microsoft Windows and OSX. TrueCrypt stores the encryption keys in the RAM of the computer.


OpenSSH is the short name for Open Secure Shell and is a free software suite which is used to make your network connections secured. It uses the SSH protocol to provide encrypted communication sessions in a computer network. It was designed originally as an alternative to the Secure Shell Software, developed by SSH Communications Security. The tool was designed as a part of the OpenBSD project.


It an open source encryption tool available on both UNIX and Windows operating system. It is a free implementation of SSH (Secure Shell) and Telnet for both Windows as well as UNIX. The beauty of this tool is that it supports many network protocols like Telnet, SCP, rlogin, SSH and raw socket connection. The word PuTTY has no specific meaning, however as in UNIX tradition, tty is a terminal name.


OpenSSL is an open source encryption tool which implements the TLS and SSL protocols. OpenSSL’s core library is written in the C programming language. The fundamental cryptographic functions are implemented by it. OpenSSL versions are available for operating systems like UNIX, Solaris, Linux and Mac OS X. The project was undertaken in 1988 with the objective of inventing free encryption tools for the programs being used on the internet.


Tor is a free encryption tool and has the capability to provide online anonymity as well as censorship resistance. Internal traffic is directed through a free network which consists of more than five thousand relays so that the user’s actual location can be hidden. It is difficult to track the Internet activities like visiting web sites and instant messages; the most important goal of this tool is to ensure the personal privacy of the users.


It is an open source tool for the implementation of virtual private network techniques so that secured site-to-site or point-to-point connections using routers or bridges are possible, also remote access is possible. OpenVPN offers the users a secured authentication process by using secret keys which are pre-shared.


Stunnel is a multi-platform open source tool, which is used to ensure that both the clients and the servers get secured encrypted connections. This encryption software can operate on a number of operating system platforms like Windows as well as all operating systems which are UNIX like. S tunnel depends upon a distinct library like SSLeay or OpenSSL to implement the protocols (SSL or TLS)


KeePass is an open source as well as free password management tool for the Microsoft Windows as well as unofficial ports for operating systems such as iOS, Linux, Android, Mac OS X and
Windows Phone. All the usernames, passwords and all other fields are stored by KeePass in a secured
encrypted database. This database in turn is protected by a single password.

  2. I seldom leave responses, but i did a few searching aand wound up here Best/Easier way to
    know more aboit your encryption tools – Skytechers.
    And I actually doo have 2 questions for yoou if you tend
    not tto mind. Could it bee simply me or does it
    appear like some of the responses come across like left by brain dead
    individuals? 😛 And, if you are writing at other
    online sites, I would like tto follow everything new you have to post.

    Coud you lst oof every one of your communal pages like your linkedin profile, Facebook page or twitter feed?
