This is a special version of Silver Key Free Edition designed for USB flash disks. It is a file encryption utility that permits users to easily secure important files and folders when moving data around on multiple computers.

In order to use this app, all you have to do is copy the archive contents to a USB flash drive and just click the executable to run. This means that you can run Silver Key on any PC with minimum effort and no previous installers.

An important aspect of portable utilities is that they do not modify Windows registry settings, nor (usually) create additional files on the hard disk without your consent, leaving no traces behind after its removal.

The interface relies on a wizard where you have to follow simple steps to get a job done in no time. You can encrypt any selected files and folders by establishing the name and format of the output container.

The program is also capable of creating self-decrypting executable files, which means that users will not need this app to decrypt Silver Key containers. In addition, it it possible to create an uncrypted text file that presents the container contents, as well as to ask Silver Key to automatically shred the source files on task completion to prevent specialized software from recovering deleted data (and adjust the number of shredding passes between 1 and 9). The password can be assigned in the last step.

Silver Key may also be used to decrypt files and folders, and to verify data integrity. When it comes to app options, you can switch to another UI language, set the tool to automatically verify data integrity on task completion and to keep the source files, and more.

The tool is undemanding when it comes to CPU and RAM, so it does not affect the PC's overall performance. It encrypts and decrypts data fast and without any issues. We have not come across any unpleasant surprises during our tests. However, there are a lot of locked features in Silver Key Free Edition, which are only available in the full package. Nevertheless, this app delivers a simple solution for securing data, and it can be used by anyone.
