FileVault logo

FileVault

FileVault is the built-in full-disk encryption feature in macOS. On Macs with Apple silicon or a T2 chip, data is encrypted by hardware by default; enabling FileVault adds a login-password gate that prevents decryption without your credentials.

LUKS logo

LUKS

LUKS (Linux Unified Key Setup) is the standard disk-encryption specification for Linux, implemented by the cryptsetup utility. It provides a header format and key-slot system on top of the dm-crypt kernel module, supporting multiple decryption passphrases per volume.

Encryption is what turns a stolen laptop or a breached cloud account into a pile of useless gibberish. These tools let you encrypt files and folders yourself, so the protection travels with the data wherever it goes. From full-volume encryption to single-file lockers, pick the one that fits.

Match the tool to the job

Different needs call for different tools. Whole-volume encryption protects an entire disk or container, ideal for a laptop that could be lost or seized. File-level tools encrypt individual files or folders, perfect for adding a layer before something hits the cloud, which is exactly what Cryptomator is built for. Lightweight single-file encryptors are best for sending one protected file to someone. Use the one that matches what you are protecting.

What to look for

Open-source code that has been independently reviewed, strong modern algorithms, and a clear, documented format so your files are never hostage to one app. Be cautious with closed “military-grade” encryption products; with cryptography, code you cannot inspect is code you cannot trust.

A free in-browser option

If you just need to lock a single file quickly, our own Encrypt tool runs entirely in your browser, encrypts with modern primitives, and never uploads anything. It is a fast way to protect a file without installing software, and the code is open for anyone to check.

Frequently asked

Whole disk or single files?
Whole-volume encryption protects everything on a disk or container at once and is ideal for a laptop. File-level encryption locks individual files or folders, which is better for adding a layer before something goes to the cloud or to someone else. Many people use both.
Is open-source encryption actually safe?
Yes, and it is safer than the closed kind. Cryptography is only trustworthy when experts can inspect it, so open, reviewed code is a feature, not a weakness. Be wary of closed 'military-grade' products you cannot verify.
What if I forget the password?
With real encryption, a forgotten password means the data is gone, because there is no backdoor. That is exactly what makes it secure. Store your passphrase in a password manager and keep a backup of any recovery key.
