Cryptology—the art of encrypting or encoding messages—is as old as humanity itself. The encryption of information has been used in wars and espionage, but since the advent of computers, access to information has become universal, making it vitally important to keep your data safe. That's why from Neoteo we bring you the five free data encryption tools.

AxCrypt

With AxCrypt you can encode your files and documents easily and securely. Simply right-click on the file and protect it by creating a password or key file. The platform's 128-bit encryption is very secure, ensuring that only the intended recipient can open it. AxCrypt is a free application available for Windows.

Cloudfogger

Continuing with a tool for encrypting files on different operating systems, it focuses mainly on cloud encryption. With Cloudfogger you can get 256-bit AES encryption for documents you upload to Dropbox, SkyDrive, or Google Drive. Cloudfogger is a free application available for Windows, Mac OS X, Android, and iOS devices.

OpenSSL

OpenSSL is an implementation of the SSL protocol (which enables encryption over the network). You don't need to install any application because SSL already comes integrated in most web browsers. This way you can use the protocol for financial transactions and other online operations. OpenSSL is an open source implementation that is frequently updated to address security issues.

DES Algorithm Teacher

We'll finish with DES Algorithm Teacher, an application that lets you learn DES data encryption. From its simple interface you can learn all encryption phases: Permutation, Permutation/Expansion, Permutation/Contraction, Xor, Substitute, and Left Shift. The platform is designed so students can learn every step of the DES encryption algorithm. DES Algorithm Teacher is a free application available for Windows.
