Kryptor is a premium open source file encryption software similar to TeraCopy, that is designed for multi-platform use for Windows, Linux, and macOS. Not only is it free, but it also offers its users a completely modern and streamlined experience as a whole.
Kryptor not only offers its users a multi-platformed and easily portable command-line tool, it additionally uses a state of the art and highly secure cryptographic algorithms. The stated aim of Kryptor is for it to be a complete blend of age and Minisign, therefore providing a simple and easy-to-use software, and as a direct alternative to GPG.
Functionality and security
As mentioned above, Kryptor is designed for multi-platform use on Linux, Windows, and macOS. Its tried-and-tested encryption capabilities do not work alone, quite the contrary. These encryption capabilities are greatly assisted by premium algorithms which include; XChaCha20, XSalsa20, and additionally AES-CBS with 256-bit keys.
Other aspects such as the main key derivation make use of the ‘Argon2’ which won the coveted ‘Password Hashing Competition’ prize in 2015. In terms of password sharing, Kryptor additionally makes use of the Libsodium ‘Sealed Boxes’ algorithm.
In-app use and GUI
In terms of Kryptors GUI, it doesn't get much simpler than this which is surprising given how complex Kryptors functions and inner workings are. In terms of encryption, the three steps are as follows: First, drag and then drop your file/folders of choice onto the in-app GUI, then choose and enter your password, and then finally click on the ‘encrypt’ button at the bottom of the page.
If you are struggling to think of a good password, a great feature of Kryptor is that it has a highly secure in-app password generator to help you get an appropriate and secure password. Additionally, to make your life easier, Kryptor has a simplified yet comprehensive ‘settings menu’ that provides you with all the help you may need for in-app browsing and more.
First-class encryption software
Given the user-friendly state of the app's functions and the benefits Kryptor provides its users, it is unbelievable that it is free. Kryptor as a whole has many in-depth and modern complexities to it yet still keeps it very simple to use.
