Proven, Simple yet Powerful

We have been doing this for over 20 years, in open source and without any known vulnerabilities.

It's perfect for the non-technical desktop user who prefers an easy and simple graphical user interface to professional and secure cryptography as well as for developers looking to integrate file encryption into their own software or their organizations' automated processes using the command line or a software development kit for .NET.

Security that stays

Our file encryption works by taking your files, one by one at your discretion, transforming them into new files with a new file extension and securely wiping and deleting the original. Once encrypted, the files can be safely moved, copied, sent and stored anywhere for example cloud storage, backup, email, local etc. The encryption always follows the file regardless of its location.

Many other encryption solutions creates a special encrypted container or folder, and when you move or copy a file out of the container or folder, it is no longer encrypted. Operating system built in encryption such as Windows Encrypting Filesystem (EFS), macOS FileVault or Linux LUKS also have similar limitations.

With our additional premium features it remains easy to work with encrypted files, automatically temporarily decrypting them to edit, read, listen or view them with the default application and securely re-encrypting them and wiping the temporary afterwards.

No Internet, No Servers

The software works entirely locally on your own device. It never uses an Internet connection, not even for update checks! This may mean a little more work for you, but you know it's for a good cause!

There are absolutely no servers used by the software that may be unavailable, taken down or hacked. You are always working off-line with Xecrets Ez and Xecrets Cli, and that's how we think it should be.

Encryption evolved

If you're familiar with AxCrypt, you'll know that it has a long history of success in it's field. You'll find that our version is a great alternative to AxCrypt. It's based on the original code from AxCrypt[2] but has been repurposed, optimized for speed and rebuilt by the original author, with modern tooling in a new cross platform package for macOS, Windows and now also Linux!

Sleeker, slimmer and more streamlined for desktop users for free, or with additional premium features at a low cost, as well as a brand new fully featured free open source command line tool for script and software integration by developers and advanced users! All 100% compatible with AxCrypt.

There's more

In addition to the file encryption software, Axantum is available for independent IT contracting, specializing in cryptography, performance optimization, high availability high transaction systems, advanced troubleshooting and all things hard and difficult within the .NET technology stack.

For historical reasons we also keep available a modern pre-built binary of the legacy version 1.7.x AxCrypt[2] software, recompiled with updated tooling and renamed to Xecrets File Classic. Finally, there's some other legacy but still useful software and documents.
