How to encrypt files with gocryptfs on Linux

Looking to harden your Linux filesystem? Gocryptfs encrypts at the file level, so synchronization operations can work efficiently on each file. Learn more in this informative article:

Gocryptfsis a Filesystem in Userspace (FUSE)-mounted file-level encryption program. FUSE-mounted means that the encrypted files are stored in a single directory tree that is mounted, like a USB key, using theFUSEinterface. This allows any user to do the mount—you don't need to be root. Because gocryptfs encrypts at the file level, synchronization operations that copy your files can work efficiently on each file. This contrasts with disk-level encryption, where the whole disk is encrypted as a single, large binary blob.

When you use gocryptfs in its normal mode, your files are stored on your disk in an encrypted format. However, when you mount the encrypted files, you get unencrypted access to your files, just like any other file on your computer. This means all your regular tools and programs can use your unencrypted files. Changes, new files, and deletions are reflected in real-time in the encrypted version of the files stored on your disk.
