Quick Encrypt

Quick Encrypt is a lightweight and easy-to-use app that can encrypt text on the fly using a password you specify. You can use it to hide secret messages when sending them to a friend via an insecure wireless network, for example, in case it will be intercepted by a hacker.

The application is specially made for computers and tablets that are running Windows 8, 8.1 and 10. Like all other signed Metro apps, it can be downloaded and installed from the Windows Store.

After launching Quick Encrypt, you can type or paste the text message in the first box, specify the password on the bottom, then click Encrypt to perform the task instantly. The password can have any number and type of characters. However, to maximize security, it's generally advisable to create a long password made from lower and upper case letters, along with numbers and symbols.

The generated encrypted message is much longer than the source, create from a random combination of characters, so anyone trying to read the text will fail to do so unless they have the correct password and use this application for decryption. The process is the same, as it's only necessary to paste the encrypted text (in the second box), enter the password, and click Decrypt.

There are no other options or customization preferences implemented by the developer. Thanks to the Windows features, which apply to all Windows Store apps, you can switch to fullscreen mode as well as take a screenshot and share the image with your friends using various programs you have installed, like OneNote or Twitter.

All things considered, Quick Encrypt proves to be a quick and simple application for encrypting and decrypting text messages using password. However, it doesn't specify which security algorithm it uses.
