Secret Review

File and drive encryption is more important today than ever. More and more users are becoming more concerned about their online safety, and keeping files and drives encrypted is most-likely one of the best ways to keep your information safe.

Secret is a lightweight piece of software that runs entirely from the command line. It is capable of running on Windows, OSX, and Linux machines and handling a wide range of encryption tasks.


Working from the Command Line

Secret has been designed to run entirely from the command line. This means that it has an exceedingly small file size and can fit on, effectively, any device or pen drive.

Working from the command line means that users will have to have some basic familiarities with executing commands, but Secret is not a demanding piece of software. Users won’t have to be command-line masters in order to get the full range of utilities from this program.

As a bonus, Secret comes with an instructional PDF that includes some sample code and basic instructions for writing your own command prompts. Secret even has some added utility features such as recursively deleting the original, unencrypted, file which removes some human error from the equation.

Unzip and Run

Probably one of the most significant benefits of Secret. The downloadable .zip file comes with a self-contained binary file, which means that you can run this program without having to install it.

If you are concerned about security and you need to encrypt files without leaving behind much footprint, then Secret is a solid choice for you.

This also means that you can run Secret from a flash drive. It makes a great tool to incorporate into your recovery, pen testing, and other mobile software needs.

Cloud Capabilities

Today, we are finding that more and more of our work is located on the cloud. This has been a significant advancement in terms of convenience, but it does represent a hazard for more secure documents.

Secret allows users to encrypt files stored on the cloud. Secret can work with OneDrive, DropBox, and other cloud storage solutions to make sure your documents are encrypted even if they aren’t stored locally on our drive.

While this isn’t a perfect security solution for cloud storage users, it does offer a robust security option that makes cloud storage notably safer.


With a file size that ranges between 15mb and 13mb depending if you pick the Windows or OSX and Linux distributions, Secret is virtually lighter than air by today’s file standards.

Three decades ago, 15MB would have been a notable file size, but today this, effectively, doesn’t take up space on your hard drive. There are likely to be image files on your device that are larger than this program.

As mentioned earlier in this review, this is an excellent choice for people working from flash drives. This small file size is perfect for such lightweight operations. It also makes an excellent choice for users with storage space concerns high on their list of priorities.

In conclusion, when it comes to encryption, if you are looking to protect your files better and you need a cross-platform program to do it, then Secret is right for you.
