I’m looking for a veracrypt/truecrypt equivalent but at the folder-level and dynamic sizing
Something like a tool which could encrypt folders in real-time and then be able to lock it up. Truecrypt expects me to provide a size for it, I’d like something more dynamically sizeable based on the files I store in it.
Even just a tool that encrypts files written into it and converts them to other files works with me
CryFS does what you want, it’s the default used by the KDE Vaults feature.
there’s also a comparison page on the site, comparing it to other solutions.
I’m assuming you don’t want a full disk encryption solution, but you can also use LUKS to just create an encrypted mount of any supported filesystem. You don’t need any type of standalone program to encrypt your things for you.
Here’s a table with multiple solutions and comparisons: https://www.cryfs.org/comparison
Just be aware that some solutions like gocryptfs are provided on a user-space filesystem (Fuse). This has a very low performance and most importantly if you require inotify on the decrypted data for some application then it won’t be available. In short inotify is what allows apps to watch a filesystem for changes and act accordingly in real time.
Tables like this suck. They are made by one of the projects in the comparison and they include no data.
Sounds like you’re looking for EncFS.
It’ll leak the size and structure of whatever you have there. Filenames and content are encrypted.
I use gocryptfs with a GUI wrapper called Vaults. It’s very neat.
