Lots of things to like:
- Built from a very mature program (I recall it was one of my first exposures to security freeware 10+ yrs ago)
- Open source (GPL)
- Uses standard AES-128 encryption
- Supports key files (assuming no one finds your key file, can be orders of magnitude more secure than a password)
- Intelligent compression (won't compress something that doesn't need it)
However, I'm not seeing why someone would use this over 7-zip, which has better compression (AxCrypt uses ZIP compression via zlib) and lots of features.
- Looks portable -- in fact there are NO settings are available to change, and this looks stealth (I had some weird system crap running at the same time so I'm not 100% sure).
- Support drag-and-drop. Maybe like our Drag-n-Crypt Ultra with that little floating box.
- Inside the file manager, double-click an AXX file (the encrypted file) to decrypt it (right now you've got to right-click it)
- Fix the odd desktop behavior: you can see folders on the desktop, but not the desktop itself. Refresh doesn't work to make folders you create on the desktop appear
- Intelligent LZMA compression (or just use 7-zip libraries)
- Other included security tools like a wipe program or something
- Text output option
- Will cache the passphrase for other files.
Wishlist: I actually like the simplicity, but I want it to support drag and drop.
Side note: interesting bit for security nerds: PC Mag
points out AES 128 is oddly better than 256
