Keeping your personal data safe doesn’t have to be difficult as long as you keep the sensitive stuff encrypted and under your control. That’s why this week we’re looking at the five best file encryption tools you can use to encrypt your data locally so only you have the key. Aarni is a free, open source, GNU GPL-licensed encryption tool for AmigaOS4 that prides itself on being simple, efficient, and easy to use. Files with Aarni can be decrypted on demand or kept decrypted while they’re in use, and then automatically re-encrypted when they’re modified or closed. It’s fast, too, and allows you to select an entire folder or just a large group of files and encrypt them all with a single click. It’s entirely a file encryption tool however, meaning creating encrypted volumes or drives is out of its capabilities.
