Encrypto is an easy-to-use utility that helps you prevent unauthorized users from accessing your private files while you're away from your computer. This program comes with a nicely-designed and intuitive interface, uses a powerful encryption algorithm, and immediately completes the given tasks without slowing down the performance of your system.
All you need to do in order to encrypt files or folders on your Mac is to drag-and-drop them over the app's interface, and enter the preferred access password and a hint (the hint is optional). In my testing, the program took only a few seconds to encrypt the loaded data.
Once the encryption process is complete, the app lets you choose between 2 tasks. You can share the protected data with other users via email or save it in a folder within your computer. To decrypt the files, just drag-and-drop them over the app's interface and enter the access password.
Other than that, not much more can be said about this utility. It's very simple to use, works fast, and is free.
Hence, you should definitely give this app a try if you're looking for a cheap and efficient way to encrypt data on your Mac.
