Trojan

Trojan is a very simple-to-use software utility that gives you the possibility to make messages secret by embedding them within images.

They are password protected, so you will need the right key to decrypt them. The tool offers support for image files with the .bmp, .jpg, .jpeg, ,gif, .mng, .png, .pcs, .tif and .tga extensions.

After a rapid and uneventful setup operation, Trojan shows a large window with an outdated look and neatly organized structure, showing all options available. You can start by indicating an image file from the computer that you can preview in the main frame.

In the bottom part of the screen you can write or paste your secret message, after which you can enter a password to decrypt it. In the following step, all you have to do is save the new encrypted image to file by establishing its name, destination and format (only .bmp, .png and .tif are supported for the output). Only Trojan is capable of decrypting images with the help of the correct password, so make sure not to lose it.

As expected, the tool didn't put a strain on the overall performance of the computer during our testing, thanks to the fact that it needed low CPU and memory to work properly. It had a good response time, encrypted and decrypted files swiftly, and didn't hang, crash or show error notifications.

Although it doesn't integrate sophisticated features, Trojan does its job quite well, providing you with a simple and fast method for encrypting text within photos using a password.
