    - [:simple-flathub: Flathub](https://flathub.org/apps/details/org.cryptomator.Cryptomator)

Cryptomator uses AES-256 encryption to encrypt both files and filenames. Cryptomator cannot encrypt metadata such as access, modification, and creation timestamps, nor the number and size of files and folders.

Some Cryptomator cryptographic libraries have been audited by Cure53. The scope of the audited libraries includes: cryptolib, cryptofs, siv-mode and cryptomator-objc-cryptor. The audit did not extend to cryptolib-swift, which is a library used by Cryptomator for iOS.

Cryptomator's documentation details its intended security target, security architecture, and best practices for use in further detail.

Picocrypt (File)

!!! recommendation

![Picocrypt logo](assets/img/encryption-software/picocrypt.svg){ align=right }

**Picocrypt** is a small and simple encryption tool that provides modern encryption. Picocrypt uses the secure XChaCha20 cipher and the Argon2id key derivation function to provide a high level of security. It uses Go's standard x/crypto modules for its encryption features.

![VeraCrypt logo](assets/img/encryption-software/veracrypt.svg#only-light){ align=right }
![VeraCrypt logo](assets/img/encryption-software/veracrypt-dark.svg#only-dark){ align=right }

**VeraCrypt** is a source-available freeware utility used for on-the-fly encryption. It can create a virtual encrypted disk within a file, encrypt a partition, or encrypt the entire storage device with pre-boot authentication.

[:octicons-home-16: Homepage](https://veracrypt.fr){ .md-button .md-button--primary }

    - [:simple-linux: Linux](https://www.veracrypt.fr/en/Downloads.html)

VeraCrypt is a fork of the discontinued TrueCrypt project. According to its developers, security improvements have been implemented and issues raised by the initial TrueCrypt code audit have been addressed.

When encrypting with VeraCrypt, you have the option to select from different hash functions. We suggest you only select SHA-512 and stick to the AES block cipher.

Truecrypt has been audited a number of times, and VeraCrypt has also been audited separately.

OS Full Disk Encryption

Modern operating systems include FDE and will have a secure cryptoprocessor.

BitLocker

!!! recommendation

![BitLocker logo](assets/img/encryption-software/bitlocker.png){ align=right }

**BitLocker** is the full volume encryption solution bundled with Microsoft Windows. The main reason we recommend it is because of its [use of TPM](https://docs.microsoft.com/en-us/windows/security/information-protection/tpm/how-windows-uses-the-tpm). [ElcomSoft](https://en.wikipedia.org/wiki/ElcomSoft), a forensics company, has written about it in [Understanding BitLocker TPM Protection](https://blog.elcomsoft.com/2021/01/understanding-BitLocker-tpm-protection/).

[:octicons-info-16:](https://docs.microsoft.com/en-us/windows/security/information-protection/BitLocker/BitLocker-overview){ .card-link title=Documentation}

BitLocker is only supported on Pro, Enterprise and Education editions of Windows. It can be enabled on Home editions provided that they meet the prerequisites.

??? example "Enabling BitLocker on Windows Home"

To enable BitLocker on "Home" editions of Windows, you must have partitions formatted with a [GUID Partition Table](https://en.wikipedia.org/wiki/GUID_Partition_Table) and have a dedicated TPM (v1.2, 2.0+) module.

1. Open a command prompt and check your drive's partition table format with the following command. You should see "**GPT**" listed under "Partition Style":

    ```
    powershell Get-Disk
    ```

2. Run this command (in an admin command prompt) to check your TPM version. You should see `2.0` or `1.2` listed next to `SpecVersion`:

    ```
    powershell Get-WmiObject -Namespace "root/cimv2/security/microsofttpm" -Class WIN32_tpm
    ```

3. Access [Advanced Startup Options](https://support.microsoft.com/en-us/windows/advanced-startup-options-including-safe-mode-b90e7808-80b5-a291-d4b8-1a1af602b617). You need to reboot while pressing the F8 key before Windows starts and go into the *command prompt* in **Troubleshoot** → **Advanced Options** → **Command Prompt**.

4. Login with your admin account and type this in the command prompt to start encryption:

    ```
    manage-bde -on c: -used
    ```

5. Close the command prompt and continue booting to regular Windows.

6. Open an admin command prompt and run the following commands:

    ```
    manage-bde c: -protectors -add -rp -tpm
    manage-bde -protectors -enable c:
    manage-bde -protectors -get c: > %UserProfile%\Desktop\BitLocker-Recovery-Key.txt
    ```

    !!! tip

    Backup `BitLocker-Recovery-Key.txt` on your Desktop to a separate storage device. Loss of this recovery code may result in loss of data.

FileVault

!!! recommendation

![FileVault logo](assets/img/encryption-software/filevault.png){ align=right }

**FileVault** is the on-the-fly volume encryption solution built into macOS. FileVault is recommended because it [leverages](https://support.apple.com/guide/security/volume-encryption-with-filevault-sec4c6dc1b6e/web) hardware security capabilities present on an Apple silicon SoC or T2 Security Chip.

[:octicons-info-16:](https://support.apple.com/guide/mac-help/encrypt-mac-data-with-filevault-mh11785/mac){ .card-link title=Documentation}

We recommend storing a local recovery key in a secure place as opposed to using your iCloud account for recovery.

Linux Unified Key Setup

!!! recommendation

![LUKS logo](assets/img/encryption-software/luks.png){ align=right }

**LUKS** is the default FDE method for Linux. It can be used to encrypt full volumes, partitions, or create encrypted containers.

[:octicons-home-16: Homepage](https://gitlab.com/cryptsetup/cryptsetup/-/blob/main/README.md){ .md-button .md-button--primary }
[:octicons-info-16:](https://gitlab.com/cryptsetup/cryptsetup/-/wikis/home){ .card-link title=Documentation}
[:octicons-code-16:](https://gitlab.com/cryptsetup/cryptsetup/){ .card-link title="Source Code" }

??? example "Creating and opening encrypted containers"

```
dd if=/dev/urandom of=/path-to-file bs=1M count=1024 status=progress
sudo cryptsetup luksFormat /path-to-file
```


#### Opening encrypted containers
We recommend opening containers and volumes with `udisksctl` as this uses [Polkit](https://en.wikipedia.org/wiki/Polkit). Most file managers, such as those included with popular desktop environments, can unlock encrypted files. Tools like [udiskie](https://github.com/coldfix/udiskie) can run in the system tray and provide a helpful user interface.
```
udisksctl loop-setup -f /path-to-file
udisksctl unlock -b /dev/loop0
```

!!! note "Remember to back up volume headers"

We recommend you always [back up your LUKS headers](https://wiki.archlinux.org/title/Dm-crypt/Device_encryption#Backup_and_restore) in case of partial drive failure. This can be done with:

```
cryptsetup luksHeaderBackup /dev/device --header-backup-file /mnt/backup/file.img
```

Browser-based

Browser-based encryption can be useful when you need to encrypt a file but cannot install software or apps on your device.

hat.sh

!!! recommendation

![hat.sh logo](assets/img/encryption-software/hat-sh.png#only-light){ align=right }
![hat.sh logo](assets/img/encryption-software/hat-sh-dark.png#only-dark){ align=right }

**Hat.sh** is a web application that provides secure client-side file encryption in your browser. It can also be self-hosted and is useful if you need to encrypt a file but cannot install any software on your device due to organizational policies.

OpenPGP

OpenPGP is sometimes needed for specific tasks such as digitally signing and encrypting email. PGP has many features and is complex as it has been around a long time. For tasks such as signing or encrypting files, we suggest the above options.

When encrypting with PGP, you have the option to configure different options in your gpg.conf file. We recommend staying with the standard options specified in the GnuPG user FAQ.

!!! tip "Use future defaults when generating a key"

When [generating keys](https://www.gnupg.org/gph/en/manual/c14.html) we suggest using the `future-default` command as this will instruct GnuPG use modern cryptography such as [Curve25519](https://en.wikipedia.org/wiki/Curve25519#History) and [Ed25519](https://ed25519.cr.yp.to/):

```bash
gpg --quick-gen-key alice@example.com future-default
```

GNU Privacy Guard

!!! recommendation

![GNU Privacy Guard logo](assets/img/encryption-software/gnupg.svg){ align=right }

**GnuPG** is a GPL-licensed alternative to the PGP suite of cryptographic software. GnuPG is compliant with [RFC 4880](https://tools.ietf.org/html/rfc4880), which is the current IETF specification of OpenPGP. The GnuPG project has been working on an [updated draft](https://datatracker.ietf.org/doc/draft-ietf-openpgp-crypto-refresh/) in an attempt to modernize OpenPGP. GnuPG is a part of the Free Software Foundation's GNU software project and has received major [funding](https://gnupg.org/blog/20220102-a-new-future-for-gnupg.html) from the German government.
