From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there a tool to real-time encrypt folders? (lemmy.world)

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

Tomb might fit your needs

Thanks I will look into it. But tomb also seems to not have dynamic sizing

You can increase the size of a tomb, but IIRC it's an offline process.

Yeah, I think as of now I will go for it

tomb looks like a nice wrapper around LUKS but it doesn't appear to support creating a sparse file, so, it will immediately use however much space you allocate to it.

(I think it doesn't support a sparse backing file because I searched the word "sparse" on their github, and for the word "seek" (which is the dd argument for creating a sparse file) in the tomb bash script, and both searches yielded no results.)
